Linux/Windows/OS X

I'm considering triple booting my PC with Ubuntu, XP and Leopard. I'm currently dual booting Ubuntu with XP. Has anyone else done this yet and could give me some advice? If anyone could point me in the direction of a good online guide, that'd be helpful. (Or is this all just a stupid idea and should I not even bother?)

Nevermind, got one. Any advice is still good though, I guess.

I have 5 operating systems at the moment. I can boot any one of them with grub. What's your fucking problem?

No fucking problem, Nutbag.  Go back to sleep.
