I have a Tab Pro 10.1. I want a 12" device and of course, the Tab Pro 12.2 is an option (are there any others?). Other than the size of the display, is the 12.2 pretty much the same machine as the 10.1 or is it bigger/better? I'm looking for a good, fast 12" gaming tablet (don't really have the $$$ for a Surface Pro 3 yet). When I got my 10.1 last year, I really wish I would have spent a little more for the 12.2.
