I use KNOPPIX and it's very fast. I would switch to it(I could buy a new hard drive and copy all the files off of the KNOPPIX cd in which case it would become Debian Linux) but none of the games today work on it. Mostly because those Microsoft assholes don't want Open Source stuff to dominate the market(which it is, Firefox is an excellent example). I could use WINE(the Microsoft OS Emulator for Linux) and it works very well on emulators for Sega Genesis and stuff like that, but it doesn't work on games like San Andreas because I think I need KNOPPIX installed on a hard drive so it can create dlls and stuff I don't know. My opinion on Microsoft: Shit-can it.
