Amadeus: If you're interested in Linux, that's awesome, but you don't necessarily have to know much about it to force your tablet to do your bidding. Most of the instructions out there are simple step by step lists. (Some can be pretty cryptic and assume you're a Unix sysadmin but most are pretty good about explaining things.) If you check out some of Penguinbait's posts here, he does a really good job of writing instructions that practically anyone can follow (and when you step back and look at the end result, it's a lot of complicated stuff.)

Anyway. If you're feeling adventurous, give Ubuntu a shot like mfresh recommended. http://ubuntuforums.org/ has insane community support. Every problem I've ever run into has already been posted and answered.
