Okay, I have a few questions about the whole bootcamp deal. Do I need a "licensed" windows disc? My father has a few burned copies that he procured from unknown whereabouts (*cough*), would those work? Also, in regards to battery life, just how many hours/minutes do I stand to lose by using XP instead of OSX? Also, any known errors that occur in XP with the new Alu macbook? Thanks for your time.
