What OS should I get??

I ws wondering should I get Windows XP with SP2, Linux(with a windows emulator), Vista (once SP1 comes out), or Mac OS X Leopard. Im going to use it for gaming, coding,video editing, and sound editing.
For What OS should I get?? try this:

• Gaming: Windows XP (nothing else really has enough games available for it, and Vista...well, avoid it like the AIDS it is)
  Everything else: OS X (though, personally, I'm partial to Adobe Audition for sound editing, which is sadly Windows-only)
  
• Windows XP service pack 2.
  The most user-friendly OS you can buy.
  
• windows Xp SP2 or windows Vista
  xp is better than Vista
  
• Go for WIndows XP servicepack 2.
  
  Its stable and have no issues.
  
  I am using it for last few years for gaming, coding, graphic designing, video and sound editing and a lot more..
