It's a good question. I really want a take-anywhere tablet in the 7-8" range, with 2GB RAM, at least 32GB onboard storage, micro SD support, LTE, a 1920x1200 or better display, and a stylus.
This actually has all that, but it sacrifices weight and battery life to provide terrific graphics performance - which I don't really care about at all. (I play games on Android, but mostly Kairosoft games and Final Fantasy, which are not particularly taxing.)
But it's by no means a bad device, and if Nvidia can refine it through another couple of iterations, and get it to a point where the extra graphics performance doesn't cost much in terms of weight/battery life/dollars, then they might really have something.
