My only comment , having just installed Vista Premium for a Media Center PC is that it is a memory hog. The PC with 1gb memory is running very sluggishly indeed. If I had a larger hard disc I would now have considered a dual boot machine...
Media Center is something of a disapointment. It doesn't record or dislpay video in HD and there is no free Australian program guide to make recording schedualing easy. The crappy VCR program that came with my HD Tuner card is starting to look pretty nifty
