We had one at work for a minute, so I tried it out on MS - the faders were too dang long - but that was before screen elements could be resized (which I've still not figured out). And I did not care for the case. I ended up with a super deal on a Nabi Big Tab 20 right before they ran out of them. The battery life is not as good (2.5 hrs), but I much prefer the form factor. I suppose it bay stop working with MS one day, as it looks as though Android 4.4 is as far as they are going to take it.
