Linux is stable, customizeable, secure, and free. It does cause headaches sometimes, but the more you use it, the easier it becomes to fix problems. I\'m using gentoo, but I dont think i\'d recommend that for a beginner. Check out Fedora Core 3 or Knoppix.
There aren\'t many games that run in Linux, but I contend that PS is the only game that matters. It is true that the linux version always comes out after the windows one, but you can alwasy build your own following the guides at laanx.fragnetics.com. It is not always easy, however.
The first time I ever installed linux on a machine, it was Red Hat 7.something, and its installer gui offered this metaphor: \"Would you by a car that\'s hood had been welded shut?\"
