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.
GMB Color Checker
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.

"Which means nothing, as these mobile chips are too underpowered to actually run the desktop x86 applications"My ATIV 500 painting an 11x17 300dpi multilayer image in Sketchbook Pro with the active digitizer smoothly disagrees with your assumption.
Just saying.

Of COURSE they run desktop programs. They run Firefox, OpenOffice (and older versions of MS Office you might already own), media tools, IM clients, all SORTS of things that aren't available or even possible on other platforms.No, it won't reasonably run Skyrim, but there's a ton that it will run.
Personally I think this is pretty awesome...you get a good for the form factor CPU that oh yeah, happens to actually be compatible with what you have, and the price is the same as ARM stuff.
What's bad is the GPU...seems like they have almost a 2009 smartphone GPU in there rather than something more appropriate for 2013...and then there's the issue that metro is locked down, not a real PC...but then that's why you want an x86 tablet to begin with...at least you get the real desktop and in that mode it's a real PC.

Basically for tablets and phones I prefer the android "library" so intel/windows really isn't for me anyways.SM123456 - Wednesday, February 13, 2013 - link
Yes, but Microsoft has to use a x86 CPU if they are to be able run Windows apps.Basically this device and all other Windows 8 tablets under $600 are grossly overpriced netbooks with touch added and a keyboard taken away.
The $199 Acer C7 Chromebook with its 1.1 GHz dual core Celeron processor is at least twice as fast as this thing.

So we have windows RT that is optimised both around the ARM cpu's and tablets. There is no old software - everything that you can get for it should both run fine on tegra 3 and work well with a small touch screen. This means stuff should just work well - this is what apple do so well, and MS are trying to emulate.On the other hand there is full windows. Now the reason to get this not RT is backwards compatibility. Most *old* windows apps require higher performance cpu's (e.g core i3) a big screen, a mouse and a keyboard. They don't use touch at all.
Taking that into account an atom tablet has a screen that's too small, a cpu that's too slow and a bad mouse/keyboard experience - sure you could plug both in but then it's not really a tablet any longer is it? Also all that backward compatibility support uses effectively a different ui - it's not a clean and polished single interface. Stuff won't just work well - the experience won't be as good.
Hence if you want full windows you'd be much better off with a laptop/ultra book - they are still touch screen so you get any touch benefits but they have much faster cpu's, better keyboard, etc.

Not sure where you got that idea from. 99% of windows applications dont hardly use any cpu at all. Check task manager sometime. You will notice that most processes only consume a few seconds of cpu time per hour of system idle time. It is extremely rare for a windows application to peg even one cpu core to 100%.freedom4556 - Thursday, December 20, 2012 - link
You that that's a percentage and it depends on what CPU you're looking at right? That's like saying, "Yeah, I never need more than 1% of my horsepower even doing 150mph uphill in a headwind." when you drive a Lamborghini. Try it again in a Honda and you'll not even be able to do it, nevermind 100% usage.Do you have an i7 or an Atom?

One thing that stood out to me in this article, is the bugs/reboots you encountered. You pretty much blamed them on Win 8, or made it sound that way. Which i thought was unprofessional, especially for you Anand. As theres a very good chance they're to do with a particular app, drivers on this device, or even it's hardware. Win 8 is a very solid stable OS, even more so than Win 7 on release.ltcommanderdata - Thursday, December 20, 2012 - link
True. But hasn't it always been the case that app and driver instability gets fairly or unfairly associated with Windows? At the same time, when things are working well, Microsoft is happy if you think of yourself as enjoying a "Windows" PC or tablet regardless of what particular software or hardware you are using in/on Windows. I guess we'll have to see how common problems are with other CloverTrail tablets. If they show up in CloverTrail tablets from other manufacturers, then even if the underlying OS is stable it still becomes Microsoft's problem if people are having trouble developing reliable apps/drivers/tablet using it.Anand Lal Shimpi - Thursday, December 20, 2012 - link
The issue is these were first party apps developed by MS, and I've seen some evidence of the same on other non-W510 platforms (I just don't remember this being the case with Surface RT but I've been using these x86 platforms longer than I did Surface).I'm curious to read Vivek's take on the ATIV Smart PC to see if it mirrors my experience.
Take care,
Anand
