The Clover Trail (Atom Z2760) Review: Acer's W510 Tested
by Anand Lal Shimpi on December 20, 2012 10:34 AM ESTThe Display
Acer uses an LG sourced 10.1-inch 1366 x 768 IPS panel for the W510. Viewing angles are great as are the rest of the basics. Max brightness is pretty low at just under 300 nits, but the flip side of that coin are very low black levels resulting in great contrast. Compared to the netbooks that Acer was shipping just a few years ago, the W510 is worlds better.
The low max brightness makes the W510 not ideal for use outdoors in bright sunlight:
Color accuracy out of the box isn’t great, but it’s really no worse than something like the Nexus 10 if you look at our CalMAN results.
Once again I turned to our own Chris Heinonen's CalMAN smartphone/tablet workflow. We'll start off by looking at the calibrated white point for these tablets. What you're looking for here is a number close to 6500K:
The next three charts look at accuracy represented as a difference between various source colors and what's reproduced on the display. The results are presented as average dE2000, with lower numbers being better.
First up is Grayscale performance, here we're looking at the accuracy of black, white and 19 shades of gray spread in between the two extremes:
First in our color accuracy tests is a saturation sweep. Here we're looking at 20%, 40%, 60%, 80% and 100% saturations of red, blue, green, magenta, yellow and cyan.

For our final accuracy test we're looking at the difference between a Gretag Macbeth colorchecker chart and the rendered swatches on these displays. Once again, lower numbers are better.

Acer doesn’t really make an effort to calibrate the display at the factory, but there’s not too much room for improvement here based on my calibration passes (I managed to get dE down to the mid 4s compared to the GMB chart). Nothing about the W510’s display really looks bad, but it does lack that extra oomph of Apple’s 3rd and 4th gen iPad with Retina Display. Microsoft did a better job on color accuracy with the panel in Surface RT. On the bright side, the display really is such a huge improvement over what we’re used to seeing from a Windows PC priced at $499.
The relatively small display size means the native resolution isn’t really too much of a problem. More resolution would always be appreciated, but in this case Clover Trail doesn’t really have the GPU to drive it. In my experience with the W510 I didn’t really find myself wishing I had a higher resolution display, although I’d be very surprised if the next-generation of these tablets didn’t ship with something higher res.

One thing about Windows 8 that continues to bug me is the way that settings are split into two areas. Some settings can be handled from the Start screen, while others take you to the desktop Control Panel. If Microsoft is so keen on this new UI, why not take the entire Control Panel and make it a Modern UI component? I get that they are trying to appeal to touchscreen and desktop users, but merging the settings into one area would help alleviate the schizophrenic feel of the OS a little bit.This is a great review, especially since I have this exact Acer tablet on the way from Newegg. My hope is that I will spend most of my time in the Modern UI, and occasionally fire up desktop software. I am hoping it will be fast to handle some older games, like Icewind Dale, and some non-CPU intense software, like the Zinio desktop app (where I can access publications that the mobile version cannot access). It's going to be an interesting experiment.
My other concern with this tablet is that it is so new, there is a very limited selection of accessories. Specifically, I am having trouble finding some sort of "gel skin" case for this tablet. There are some generic fold out tablet cases, but those are bulky.
By the way, I had hoped to get an AMD Windows 8 tablet, but where are they? I love AMD, but I have to buy based on my needs and what's available, and right now Intel has the only real x86 solution for Windows 8 tablets.

"The power adapter itself isn’t anything remarkable, however Acer did use a nifty removable plug that easily twists on/off. The W510 only ships with the plug for whatever region you purchased it in so I’m not sure how useful this feature is, but it’s nice to see design innovation from Acer here."Just for the record, this is not new. Apple's power supplies for MacBooks have done this for, I don't know, 8 years or so. The power supply has a core that is common, and a regional plug that can be slipped on or off. See here:

iPad power adapters are the same. iPhone/iPod are not, I expect because they are so small that they are basically the size of the dongle that would plugin to the socket, so modularizing them this way would basically double their size.
I've no idea if this is original to Apple or not, but it's certainly not original to Acer.

I don't think you understand the mechanism. Apple uses a friction fit with a straight downward motion. The connector that Acer uses rotates on, which you can see in the picture the directions to operate. All of the other adapters I've seen (including miscellaneous ones over the years) have been similar to Apple's, usually with a mechanical clip. Acer's method is innovative, but I'm not sure what advantages are offered by it.lorribot - Thursday, December 20, 2012 - link
It's things like that 11GB recovery partition that show how far MS have to go in the light weight sector. The 13 GB for Windows, which will bloat massively with patches and installs is another example of them playing the wrong game.My windows & folder is a typical 21GB add to that a 11 GB recovery partition and that leaves nothing for user docs or programs on a 32GB model.
It would make more sense to stick the recovery partition on a 16GB USB stick or SD Card and use that to recover the system should the need arise and give back some of the expensive internal storage space to the user.
Windows 8, good first attempt but wait for Windows 9 when they fix all the things they didn't have time for and realise two into one doesn't go.

Yeah, I was amazed by that 11GB figure.As a point of comparison, the OSX recovery partition is 650MB in size.
Now it it possible that the Win8 recovery partition does more (as opposed to "has more to do [because there are more things that can go wrong]"; I'd be interested in an informed comparison of the two, and a dissection of just what is taking up all that space.
Is it sheer incompetence (for example including 64 bit binaries on a 32bit system)?
Is it including every human language on earth?
Is it because no-one bothered to make an effort to include only the bare minimum OS+support frameworks (as opposed to including the AV subsystem, and .NET, and fifteen ways to talk to a database, and support for MS Office, etc etc etc)?

They do need to do something about the humungous recovery partition, but... you can put the recovery partition on a thumb drive or other removable media and free up that 11GB, if I'm not mistaken.secretmanofagent - Friday, December 21, 2012 - link
It's an incorrect comparison, as the restore for OS X requires an Internet connection."In order to reinstall OS X Lion or OS X Mountain Lion, you will need to be connected to an Ethernet or Wi-Fi network."
"The OS X download is about 4 GB large;"

Yes and no for the Apple restore.The recovery partition has tools that can do a bunch of things, for example run a fsck on the boot drive. If your problem is the sort of thing that can be fixed by fsck, ie some localized damage to the file system, then you will not need the internet connection.
You will need it (sortof) if you want to reinstall the OS.
If MS have the entire OS in their recovery partition, the size makes more sense, but seems more than a little foolish --- wasting so much fast expensive flash when you could ship a cheap USB stick.
In the case of Apple, it is fairly trivial when you first download/install Lion or Mountain Lion to burn a copy to a USB stick, and to use that copy if you don't have an internet connection (or have a slow connection, or pay per MB downloaded, or whatever).
I do think it's less than ideal that they don't include a USB stick of the OS with new machines (they did with the first few iterations of MacBook Air), but it's possible that their numbers tell them that pretty much no-one ever needs to reinstall the OS --- the tools of the recovery partition are acceptable for pretty much all problems. Certainly in my experience that's been true, for both my and friend's machines. I have no comparable experience with Windows.

Microcenter has the 32GB model on sale for $399, so I took a chance. Your review pretty much matches my conclusions as well. It's generally a nice device, CPU performance is good, etc. The major disappointment for me was terrible game performance. I had lag and choppiness playing Solitaire! In late 2012?! I want to like Windows 8, but to have a card game take up almost 100MB of precious eMMC capacity is just sad. Until storage default size balloons significantly, it's hard to get on board with MS right now.Another thing MS needs to work on is the keyboard auto-correct, or the lack of it. The onscreen keyboard offers no assistance, and text selection is a nightmare. In IE, I could never select text, as double tapping just kept zooming in and out. It was quite frustrating.
I found the camera and its respective app to be horrible. Not just bad, unuseable bad.
I really really wanted to like the W510, but I ended up exchanging it for a Transformer Infinity. I am much happier with it.

As far as the text selection thing goes, if it's anything like Windows Phone, you don't double-tap to select things (as you noticed, that zooms). You long-press instead. It's a little odd if you're in the habit of double-tapping from iOS/Android, but it works just fine for me on my Windows Phone.
