It's a great tablet.
I purchased a 2520 on the first day it was available at AT&T and I love it. It has a great form factor and terrific battery life. There is a bug where it occasionally won't wake from sleep mode and I need to do a soft reset, but it hasn't happen frequently enough to be a real problem. The LTE radio is what makes this tablet a gem amongst other Windows tablets. Most of this time I have Wi-Fi available, but there are plenty of times that having LTE is really convenient. The fact that it uses Windows RT isn't a show stopper. I never faulted the IPad for not having x86 support, I not going to fault Windows RT either. The app store does have less options, but in reality, it has all the tools that I need, Office, Citrx, Remote Desktop, and a bunch of great games to keep my two year old busy. I like the Xbox service integration and have already rented movies and put them up on my plasma via the mini HDMI on the 2520. In my opinion, the 2520 is a great tablet for a great price.
