hi guys, my imac c2d will be arriving in a day or 2 and i will be bootcamping it. but i have a couple of quick questions. if i install the vista rc1 how long will it last (to release?) and when it runs out i doubt i will buy it for the price will it be easy to just install xp on the partition or will that be a pain process? thanks guys. trying to be prepared for a nice setup experience on arrival.
