Running WinXP on a Mac

[zipzap]

I've just run Boot Camp on a couple of work MacBooks and now I am able to choose between XP or OSX when I switch them on. It all seems to be running fantastically well - just wondering if anyone else has messed around with this, have there been any pitfalls or has it been smooth sailing? Any Windows software you've had problems with? What about playing graphic intensive video games - any dramas?

Personally, if this works out, I'm thinking my next computer will be a Mac if it can successfully run two systems.
