It's a good sturdy tablet overall. The rubber backing is great and that's why the gf took it from me! I feel safer w/her using that anyway as electronics have a way of slipping out of her hands!
2011 was the year of Tegra2 tablets so there's not that much to differentiate it spec-wise but the rubber backing and full-size SD/HDMI did it for me. The SD card saved me in a pinch when we wanted to get pics from someone's digital camera.
I've also got a rooted B&N Nook, Viewsonic Gtablet, Asus W500 (running Windows 8) and multiple other laptops - the Thrive is used the most out of all of them (but mostly by her!)
