So I just bought my new tablet pc and love it! However, vista is pretty slow and a little bulky. So I did some research and found Linux and I'd like to put the new Ubuntu OS on my computer, but I have a couple of questions: 1) What are the compatibility issues with the tx2z and Linux? I heard of problems with the ATI graphics cards, what about N-trig, and what about multitouch? Are there any solutions to these problems? 2) I'd still like to keep vista, mainly because I'm not ready to make the complete switch yet and I like to play video games, but I would like to keep it off my hard drive: I'm not geeky enough to feel brave in the "screwing around with my hard drive" department. Can I run my computer on Linux off of an external hard drive via USB? 3) And how difficult is installing all the drivers, programs, applications, etc.?
