Is it worth getting the new mac mini? My gf needs to use windows from time to time for school but prefers to use os x (her primary machine is a 12" powerbook). We have a PC, but I am looking to sell it to a friend of mine. We already have a monitor and whatnot so an iMac is sort of out of the question, though i am thinking about that too. What are peoples experiences w/ the mini, also with running the mini in windows from time to time. Thanks.
