Full-time freelance writer, researcher and occasional expert witness, I specialize in Windows operating systems, information security, markup languages, and Web development tools and environments. I blog for numerous Websites, still write (or revise) the occasional book, and write lots of articles, white papers, tech briefs, and so forth.
In the past two weeks, I’ve set up half a dozen PCs, mostly in the wake of clean installing or upgrading them to Windows 8.1. Along the way, I’ve encountered numerous software elements that seek to get users to install additional software programs so they can get access to sometimes essential plug-ins, programs, and other stuff.
To be more specific, I’ve encountered the Ask toobar and search replacement items along with adding Java to those machines, as well as the AVG toolbar and search tab insertion into most Web browsers (which means Chrome, IE, and Firefox on my production PC, and also includes Safari and Opera on other machines as well) for Adobe Flash player (here’s a whole list of vendors who include the AVG Toolbar as part of their product installs).
Booting the Secure Search tab in Chrome proved to be quite an effort.
I got stuck in a particularly nasty uninstall problem with AVG Secure Search and Chrome, in fact. I used Revo Uninstaller to get rid of the installed elements, and then had to go into the Web browsers to root AVG Secure Search out of their defaults and settings, one at a time. My issue with Chrome persisted until I realized that the “On Startup” item in Settings provides the ability to add multiple tabs when the program starts up. That was where the remaining invocation of AVG Secure Search remained untouched and unstopped, until I figured out I had to manually delete that entry from that part of the browser configuration.
I understand that companies often partner up when offering free and popular or widely-used software to the public, and permit third parties with money to spend on purchasing installs who feel like they have something to gain by paying to come along for that ride. But what I don’t understand is why some of those third parties feel like they have to resist user attempts to avoid such maneuvers, sometimes to the point of making such installs feel more like drive-by malware than like legitimate commercial software.
I have long regarded AVG as among the best of the free malware protection makers, and their consistently high ratings from Virus Bulletin, PC Magazine, and so forth indicate that their malware suite is decent software. I am dismayed that they would use their knowledge of how software hides from users against the very users they so ardently seek to protect.
I feel the same way about any tagalong items that don’t clearly advertise their presence and provide clear, obvious, and usable opt-out mechanisms so users don’t end up installing software on their machines that they don’t really want. I don’t exactly love the idea of having to watch installers closely at all times on vigilant lookout for opt-out messages when they appear, either, but it definitely beats having to take the extra software as a consequence of the software you want, and then having to uninstall and clean up after the unwanted stuff manually after the initial install is ended.
On October 22, I posted a blog here entitled “Interesting Adventures with iCloud and Outlook 2013” wherein I recounted some difficulties with making those two software components play nice with each other in the immediate aftermath of my upgrade from Windows 8.0 to 8.1 on my production machine. Having now waiting a little over two weeks for more collective wisdom to coalesce online, I’ve found my way to a solution of those difficulties.
I’m now using the iCloud service, trying to get better synergy between my desktop and notebook PCs running Windows (8 or 8.1) and my iPhone and iPad (now both running iOS 7). By and large things are going reasonably well, but I noticed some glitches in the past few days after upgrading my production desktop to Windows 8.1 GA (from the September version of the 8.1 called RTM). I wasn’t expecting too much to change between RTM and GA, and mostly that’s been a sustainable supposition, but a few things have changed in surprising ways. And alas, some of those changes have not been for the better…
Case in point: I recently installed the iCloud Control Panel applet on my production desktop, when that system was running Windows 8.1 RTM. To my immense suprise, when I next went to visit My Contacts in Outlook 2013, the contents of the local My Contacts folder was empty. But because I could access the same information online through the iCloud folder instead, I thought to myself at the time “Good thing I’ve got a backup” and also “I can’t believe they decided to remove local data altogether instead of synching local and remote copies.”
That’s why I wasn’t completely bollixed when, in the wake of the 8.1 RTM-to-GA update, iCloud stopped working in Outlook 2013. Instead of accessing the cloud version of my contact data, when I click on iCloud in the Contacts view in Outlook, I get an error message window that reads: “This set of folders cannot be opened. The information store could not be opened.”
So what did I do? I went to my backup PST file and used the Import command to grab the Contacts folder from that file and bring it back into the local copy inside the resident PST file on my production desktop. I got my contacts back without too much fuss and bother, but I still can’t help wondering, yet again: Why did Apple decide to take the only copy of the data and put it in the cloud, so that if you lose access to the Internet (or in this case to the necessary “information store” on the Internet) you can’t access your contact data, either. Not at all.
I have trouble understanding how a software designer could cobble together a system that could so easily deprive a person of his or her contacts. For those of us who, like me and countless others, depend on that information for their livelihoods, that kind of catastrophic loss of access is simply not acceptable. In my case, I knew exactly how to work around it. But I know many others who would be crushed by this loss, and who might not have a backup PST file from which to pull the information. It’s still accessible, by the way, through a login to iCloud.com on my account there — it’s just no longer programmatically accessible to Outlook, for whatever arcane reason broke the Outlook to iCloud connection.
Sure hope Apple or MIcrosoft, or the two of them in tandem, get this fixed sometime soon! I’d also suggest that they give users the option of creating a local backup during the iCloud install process, with some instructions on how to restore that backup should it become necessary. It wouldn’t take much extra effort, though it could confer considerable increased peace of mind.
Here’s a list of instructions that I had to follow on my Lenovo X200 Tablet, to remove an issue with the WAN miniport (#2 and #3) drivers on that machine, whose failure to load up and register properly also rendered Bluetooth inoperable on that machine when running Windows 8 (or 8.1, as you might expect; this material is fully documented in KB article 2871372):
Who came up with this mysterious fix, and how they did figure this out? Wowie-zowie!
Open Device Manager.
Right-click the WAN miniport (Network monitor) device, and then click Update Driver Software.
Click Browse my computer for driver software.
Click Let me pick from a list of device drivers on my computer.
Clear the Show compatible hardware check box.
In the column on the left side, select Microsoft, and in the column on the right side, select Microsoft KM-TEST Loopback Adapter.
In the Update Driver Warning dialog box, click Yes to continue installing this driver.
After the driver is installed, right-click the device, and then click Uninstall.
After the device is uninstalled, right-click the computer name in Device Manager, and then click Scan for hardware changes.
On the View menu, click Show hidden devices.
The WAN Miniport (Network monitor) device should now be started and no longer have a yellow exclamation mark next to it.
For reasons that go way beyond my ken but that I find egregiously irritating, this bit of mumbo-jumbo actually worked! To me, it seems almost like turning widdershins thrice, hopping on one foot, while making an incantation, to try to make something happen. Arthur C. Clarke said that “Any sufficiently advanced technology is indistinguishable from magic,” and I’m damned if I can really tell what’s up here, other than the bizarre reality that installing and then uninstalling a nugatory driver actually results in proper recognition of the underlying hardware, and automatic installation of the correct driver when the next hardware rescan occurs.
There is just a glimmer of a suggestion of what’s really going on here in the “Resolution” section of the related KB article. It says that MS Update 2822241 must be “integrated with” (which I believe means slipstreamed into) the installation image (WIM file, probably) used during setup of Windows 8 for target hardware to avoid these contortions. That tells me that the update rollup in that particular update file somehow fixes the issues discussed in 2871372, even though it’s not specifically called out in the “Issues that this update fixes” in its supporting documentation.
What galls me about this fix (which I’m very grateful to have found, and am now able to use Bluetooth devices on the X220 Tablet) is that it’s so very arcane and non-intuitive. I’m able to address most driver issues in Windows on my own, with a bit of elbow grease, and lots of odd and interesting techniques for extracting driver files from installers for software that won’t run on my systems. I’m OK with that, and have learned how to cope. But installing a loopback driver, and then removing it, to provoke a proper hardware scan for device recognition? The mind reels…
Drat! My production machine has started to act up lately. Yesterday was a pretty extreme example, as this trace from Event Viewer will show:
The system restarted four times yesterday, but because it was a Sunday, I couldn’t observe what happened.
The system has been getting increasingly, but not unbearably flaky over the past 3-4 months. My symptoms include: no records being written to my Reliability Monitor files (I’m pretty sure this is an unwanted side effect from Soluto), occasional issues with the Acronis Scheduler Service (which doesn’t always start up properly after a reboot), and lately, repeated sit-downs at the machine in the morning to a login prompt (I usually leave it running all the time to do backups and updates in the wee hours of the morning). This latter condition indicates some kind of BSOD may be occurring. I’ve disabled the MSI Afterburner, which overclocks the Nvidia GeForce GTX 460 in my system, because I just updated to the latest drivers, and noticed the video driver started acting up almost immediately thereafter. Since then, no trouble at all…
But anybody who’s messed with Windows for any length of time will know what I mean when I say that these systems’ stability tends to degrade over time if, like me, you’re always installing and playing with new software (sometimes beta, sometimes not), and then de-installing much of the experimental stuff later on because it’s not worth keeping. These days, I try to restrict that sort of fooling around to VMs instead of the base OS, but I still install (and later remove) a great deal more software than is typical for a typical end user installation. If history is any guide, that means it’s time to de-gunk my Windows machine. Ordinarily, that would mean wiping the boot/system drive, performing a clean install of Windows 7, and then reinstalling all of my applications.
But now, I have to consider whether or not I should simply upgrade to Windows 8 instead. I’ve been using that OS for over a year now, and am comfortable enough to use it for production work. It’s also got some very nice features I like a lot — better security, native mounting for ISOs, the ability to snapshot a current install for the “Refresh your PC” operation, and a bunch of other stuff I’d like to use better, and more often. Maybe that means it’s time to take the plunge? I’m starting to think so, but…
…that means I need to find a full day to dedicate to making the switch. My real problem is, I have so much work to do right now I don’t know when I can find the time to perform the cut-over. But with increasing instability, my experience teaches me I’ll be doing it sooner or later anyway, just because my production system is trembling on the threshold between tolerable instability and intolerable instability. For the time being, I guess I’ll just work as hard as I can to try to free up some time in my schedule. Maybe next week? I’ve got my fingers crossed!
[Note added 3/5/2013: As I continued to ponder the “Win8 vs. Win7” decision I came across a ZDnet post from long-time OS expert Steven J. Vaughan Nichols which graphed the uptake of Windows 8 versus Windows Vista, each over the first five months since their respective introductions. Here’s the graphic he produced to present a stark and scary comparison:
Across the board, Win8 underperforms Vista! Graphic reproduced from Steven J. Vaughan-Nichols ZDnet Web post entitled “5 Reasons Why Windows 8 Has Failed” with the author’s permission. Please read the original article in its entirety for a sobering (re)view of the sad and sorry state of Windows 8.
Although sales of Windows 8 may be strong, Vaughan-Nichols’ chart makes it clear that sales haven’t yet translated into an equivalent number of Windows 8 users on the Internet. This has pretty much stopped me dead in my tracks, and I’m seriously considering flip-flopping my decision, and re-installing Windows 7 instead. That said, I did upgrade to Vista and found it to be a stable and dependable OS once the marketplace remedied the initial driver incompatibility issues that drove early adopters so crazy. I’m still thinking…]
I’ve got numerous PCs around here and there — I can see two desktops and two laptops as I sit here in my office, and there are two more laptops and one SFF desktop elsewhere in our domicile at this moment; I’ve also got four laptops out on loan right now to various friends and relations. My wife and I both use iPhones (both are 4S models), and we’ve got a family iPad, plus a 32 GB iPod that Gregory used to play on a lot before he got a Nook for his birthday earlier this month. That means we have no shortage of machines into which we might plug one of these iDevices, but there’s an issue in working with them that I wanted to avoid on those machines where I don’t usually play iTunes music or watch much video.
The conundrum pretty much boils down to this: the iPhone driver that Windows loads on its own is pretty ancient, but unless you want to install iTunes, it’s a tricky business to get a more up-to-date driver without carrying all the extra iTunes baggage along with it. Believing there had to be a way to get the drivers without the full-blown package, I searched Google using this string “install iPhone drivers without installing iTunes.” And sure enough, up pops a free utility named CopyTrans Drivers Installer that will do the job for you (here’s a C|Net download link for the 3.35 MB utility in ZIP form, just like the afore-linked product page itself proffers). Download the file, unzip to a directory, then run CopyTransDriversInstaller.exe (version 1.024 as I write this post), and you’re done. Not much to it, really.
The initial run screen requires you to agree to the licensing terms.
There is one catch, however: the program will download iTunes in its entirety, then extract the drivers from that download and install them for you. That’s what the Automatic install option at the lower right of the installer window above is about: it’s well worth using, because it does all the grunt work for you. It also works with the latest and greatest iTunes download available from the Apple site on your behalf — that was version 11.0.2.26 as I wrote this post — so you don’t have to check or worry about version numbers, either. The iTunes download (it’s nearly 86 MB in size) took far longer than any other parts of the installation activity. Though the whole operation took about 8 minutes or so on my Lenovo T520 laptop, more than half that time was devoted to downloading iTunes so the program could extract the drivers contained therein for installation (which took well under a minute, when it finally got underway).
If you want to dock your iDevice to a Windows PC without installing iTunes, it’s probably worth grabbing a copy of the CopyTrans Drivers Installer. Put it through its paces, and you’ll have the latest and greatest iDevice drivers at your disposal without having to shoulder the burden of iTunes (and the Bonjour protocol, iTunesHelper.exe, and anything else Apple decides to throw into the iTunes mix — see this fascinating and horrifying list of background processes that can show up when you use iTunes on a Windows PC, straight from Apple Support).
[Querelous and Concluding Unscientific Postscript, with apologies to Kierkegaard: I’d love to know what tool or technique the CopyTrans Drivers Installer uses to access the contents of the 32- or 64-bit iTunes installer files. I attacked them with both 7Zip (which is suprisingly capable at taking .exe files apart) and Legroom Software’s Universal Extractor (which is a good tool, but hit or miss, and crashed when trying to unpack this file’s contents) without any luck. Knowing how they did their thing would help me do it with other installers, which is sometimes the only way to get access to Windows drivers that may not otherwise be accessible on some PCs, particularly when, for example, trying to snag a Dell driver for use on an HP machine, or vice-versa.]
I’m in a bit of a quandary on an interesting subject. I just purchased a 128 GB USB 2.0 Flash drive — a Centon DataStick Sport — that I picked up on special from TigerDirect for about $65 (as I write this blog, you can pick them up at Amazon for about $80). It seemed like a very good deal when I bought the unit, but I was quickly disabused of my enthusiasm when I plugged it into my desktop PC to copy all 29 GB of music I keep on that machine to see how it performed doing large bulk file transfers. The entire transfer took almost three hours to complete (I can do it in under 40 minutes from one direct-attached disk to another), after which I understood that while I might have purchased plenty of capacity, I didn’t get the kind of performance one might wish to have, to keep the time required for big file transfers more manageable — but then I didn’t pay for that privilege, either.
This flash drive is big (128 GB) but it’s not fast.
At least, I now understand why USB 3.0 or eSATA makes more sense for big flash drives, or other forms of external storage, especially if you need to move large amounts of data on a regular basis. But if you go shopping for USB 3.0 flash drives (probably the most practical form of higher-speed flash storage available at the moment) you’ll find prices running from $1-2 GB for such storage, depending on how fast you want that storage to be. In particular, the bigger and faster such drives get, the more they cost. In particular, this $290 Super Talent 100GB USB3.0 Express RC8 Flash Drive (model ST3U100R8S) stuck me as amazingly extravagant, even if it is “Windows To Go certified” for Windows 8 Enterprise.
On the other hand, you can jump over to Newegg and purchase a Vantec NexStar 3 USB 3.0/eSATA 2.5″ drive enclosure for $30, and a very fast Samsung 830 128GB SSD for $105. Add $20 for shipping and handling, and you’ve spent $155 for more storage capacity (119 GB actual storage in Windows Explorer vs. 93 GB likewise) and similar or better speed (depending on whether or not your notebook has an eSATA port or “only USB 3.0″). Given those economics, I have trouble understanding why anybody would buy the higher-dollar UFD, except that the form factor is significantly smaller. But my Vantec drive measures out at about 5.5 x 3.5 x 0.7” and weighs under 250 grams, so it will fit into a laptop bag with no stress or strain at all. And it only takes 5 minutes and a Philips-head screwdriver to put all the pieces together.
But there must be a market, because there are lots of 64 GB and higher-capacity USB 3.0 UFDs available. Go figure!
Through a strange series of events, I got selected to fill Dave Strom’s inestimable shoes at the Dell Customer Advisory Panel (aka DellCAP) meeting in 2011. Since then, I’ve been a member of that sometimes stormy, sometimes sedate, but always interesting group and have provided my input and insight — such as they are — to this hard-hitting group of social media mavens, digital community activists, and consumer rights advocates.
Such memberships apparently come with some interesting privileges, too. About two weeks ago, I drove over to the Parmer Lane Dell campus in northeast Austin to pick up a brand-spanking-new XPS 13 laptop, issued to me on more-or-less permanent loan. The reason for this largesse: the DellCAP members get issued with such a machine to work and play with as they see fit, and write about as they please. So that’s what I’m doing here: sharing my first impressions of this svelte but powerful laptop (current MSRP is around $999) after spending some time getting to know it, and using it for a variety of tasks.
Right out of the box, there’s a lot to like about this snappy little unit, which lots of reviews compare to the MacBook Air. This is a flattering but apt comparison if you ask me, as the owner of a 2010 vintage MacBook Air myself (Core 2 Duo, nVidia GT320 graphics, and 256 MB SSD). The Dell unit is about 0.5″ narrower, but almost the same depth and thickness; the Apple unit weighs 3 lbs 7.7 oz, and the Dell comes in at 2 lbs 15.1 oz. The comparison remains favorable throughout, in fact. Here’s a look at the out-of-the-box Windows Experience for my XPS 13:
Not bad for an Intel HD 3000 based graphics architecture
Battery life for the XPS 13 is all over the place, depending on what you use the unit for. Continuous WLAN and/or streaming video cuts the typical light-duty battery life of about six to six and half hours to around three to three and half hours. This prompted a nice blog post on the Official Dell Corporate Blog entitled “Maximizing Battery Life on the XPS 13 Ultrabook…” that’s worth a read for those seeking to eke more minutes (or hours) from their units. Overall, battery life is not as good as a MacBook Air (one of the few areas in which the Apple unit comes off best in such a face-off) but it’s not bad, either.
Intel Inside — and More!
The CPU is an Intel i5-2467M, a 1.60 GHz dual core CPU that supports hyperthreading (and shows four processor threads in various performance displays) and includes 3 MB of L3 cache, 2×256 KB of L2 cache (one for each core), and 2×32 KB for data and instructions L1 cache (one for data, the other for instructions, natch). The XPS 13 includes 4 GB of Samsung DDR3-1333 RAM (2×2048 MB modules, not upgradeable), and a zippy Samsung 128GB PM830 mSATA SSD (actual size: 119.24 GB as reported in the Windows 7 Disk Management console). The GPU is an integrated Intel HD 3000 which is fine for my laptop needs (I don’t play many shoot-em-ups or RPGs on such machines) and the 1366×768 glossy Gorilla Glass-covered monitor delivers sharp, clear video as long as I don’t try to work outside or in bright ambient light (in which circumstances, screen glare definitely impairs the display’s visibility).
There aren’t many ports on this puppy, either, thanks to its slim lines and svelte exterior. There’s nothing on either the front or back edges, and here’s the layout for each side of the XPS 13, from rear (hinge) to front (palm rest and touchpad):
Left: Power port (which leads off to a tiny 45W brick 3.5×1.875×1.125″), USB 3.0 port, headphone jack
Right: Mini-DisplayPort, USB 3.0 port.
The keyboard features a white back-lit layout with a standard QWERTY deck and nice-sized shift, caps lock, and tab keys at left, and a big backspace, enter, and shift key at right. The top row features half-sized function keys (F1-F12) plus mute, insert/print screen, and delete keys. The far lower right also offers half-sized arrow keys that double as home (left), page up (up), page down (down), and end (right) keys. Far lower left offers Ctrl, Fn, the Windows, and Alt keys with a big spacebar to the left of another Alt and Ctrl key (and then the arrow keys). Typing on the keyboard is a generally positive experience, and requires less time for me to adjust to than some of my other notebook/laptop PCs, some of which — especially my HP HDX9203 “Dragon” — feature what can only be called “wonky” keyboard layouts. For routine e-mail, light typing, and so forth, this keyboard is quite nice to use.
More on the Zippin’ Samsung SSD
The Samsung PM830 mSATA SSD produces some tasty benchmark values in CrystalDiskMark, and is certainly the fastest laptop SSD I’ve had occasion to work with (the rest of mine are mostly SATA II, and by no means real screamers, unlike some of my desktop units which include an Intel 520 and an OCZ Vertex-4). As my earlier Windows Experience screen cap clearly shows, the disk is the fastest thing about this system.
The Samsung SSD posts some serious disk performance numbers
Fresh from the factory, and…
The XPS 13 showed up with little or no bloatware. The next sequence of screencaps shows my XPS13 with its full complement of software. Of what you see in that list of 55 programs, I installed 17 of them: 7-Zip, Adobe Flash and Reader, CPU-Z, Dell Driver Download Manager, Everything, FileZilla, Image Resizer Powertoy, Intel ProSet Wireless stuff (2), Intel WiDi, ISO Recorder, MS Office (2), Secunia PSI, System Requirements Lab for Intel, and WinDirStat. The .NET Framework 4 elements are probably my doing as well. At any rate, this is not what I would call “a load of crapware” as the following list will attest.
Almost everything Dell includes has its name on it
The only Dell element that’s earned a “grrrr” reaction from me so far is its Dell DataSafe Local Backup software: it really doesn’t work as you’d want it to unless you purchase a $39/year “upgrade.” With Windows 7 offering perfectly usable image and file backup through the built-in Backup and Restore facility, I didn’t really see any compelling reason to use the program, nor to pay the upgrade fee. I am fooling around with the Dell DataSafe Online, but with only 2GB of free storage, so far I’m just using it for such stuff as I actually keep in the folders associated with my User identity/account name (18.95 MB, according to the most recent reading).
I also decided to upgrade my system from Windows 7 Home Premium to the Ultimate edition (thanks to my MSDN subscription, this comes as part of that $1,000 a year or so payment, along with most of my other various Microsoft licenses). I’m not sure this was “absolutely necessary” but I like to use the Remote Desktop Connection (and RDP) to remote into my laptops and other systems, and Windows 7 Home Premium doesn’t support such use. I guess that makes it a “nice-to-have convenience” for which I’m appropriately grateful.
What to Make of Dell’s XPS 13
At $999 for the model I’ve got, the XPS is no cheap notebook/laptop. It’s a real ultrabook, with the small size, light heft, and snazzy good looks and accoutrements you’d expect for that kind of money. It’s very usable, friendly, and powerful enough to satisfy all but the most power-hungry programmers, system admins, and heavy-duty tech types. As ultrabooks go, the XPS 13 offers a nice enough price/performance ratio to be worth purchasing, and it makes a great road machine, too.
This year, school is getting serious for my 8-year-old son, Gregory: he’s in the third grade. For the first time, he’s having to deal with real grades for his homework, plus regular quizzes and tests. And later on this year, he’ll face his first standardized test (the Texas Assessment of Knowledge and Skills, or TAKS) as well. He shares a classroom at Cactus Ranch Elementary with 18 other kids, but they have only one general use laptop for the whole group there (the kids do have more general access to computers in the library, and some classes issue laptops to students from cart set-ups for their use as well). His classroom PC is an elderly Dell D630 Latitude that’s on the last phases of its lifecycle — I volunteer in the library once a week, and the school IT guy also works there; he tells me they’re getting ready to upgrade to Vostro models running Windows 7 in 2013.
So I’m loaning my son’s teacher a couple of additional laptops for the kids to share in his classroom. One is my old and trusty Dell D620 Latitude that’s been upgraded with an OCZ Agility 3 SSD, 4 GB RAM, and a T7200 CPU (which puts it on par for processing with the D630, but where its SSD blows the doors off that unit). The other is my equally old and sometimes not-so-trusty HP HDX9203, aka “The Dragon.” I decided to roll the Dragon back to Vista SP2 and it’s been running like a champ ever since. However, Vista’s odd and seemingly random Windows Update behavior hasn’t let me believe I’ve finally caught up with all the updates: with 148 of them installed over the past two days, it’s been a dizzying sequence of download-install-reboot the entire time. Even so, Windows Update now claims I’m completely caught up. We’ll see.
The D620 has an adequate 14″ screen.The HP has a huge and vibrant 20″ screen.
I’m still debating as to whether or not I should install Paragon’s terrific $20 Migrate OS to SSD utility on the Dragon, and then use it to move the OS over to the spare OCZ Vertex 2 nominal 120 GB (actual 111 GB in Windows Explorer) drive I’ve got lying around. There’s no doubt this would speed things up significantly on the Dragon, just like the Agility 3 did for the aging D620, which laughably melds a processor rated at 5.1 in Windows Experience with a drive rated at 7.8! But there are few things you can do to an older laptop to keep it usable that are better than this, so my real question is: do I want to let the Vertex 2 walk out the door, or do I have something better I can do with it? Right now all of my laptops and desktops boot from SSDs already, so perhaps not…
