If you're big on Linux, try that microwindows thing - it should run on lowspec hardware. KDE is slow on my 233mhz PC - God knows what it's like on a 486. One other possible market, however, is for people who can't learn computers. I have a friend and a mother in this category. My mom's post heart op and has lousy short term memory, but is trying to learn how to use a PC. She's trying HARD, but cannot remember simple stuff. I've yet to find an email client that's so simple it doesn't have to be learned - if I did, she might be able to use it. I know kids are supposed to learn, but maybe an interface that's so simple a 4 year old could understand it is just what my mother needs...! Have fun...
