just so you know, maybe others can confirm or correct me on this, I'm pretty sure your warranty is invalidated as soon as you install windows on your mac?
Someone's offered me real cash money for this laptop, so I'm definately looking for one now, and if that's true, then fuck getting a Mac.
Plus, the free warranty Baz was on about isn't coming up as being free when you go to buy it, do you have to buy it over the phone?
edit.
After a quick google, people are saying Bootcamp comes installed now as part of OSX, so surely Apple will be fine with you installing XP, as if they don't want you to, what's the point of having the facility available?
