plastic-junk virus-laden pc...meh.
Another reason for the Macbook: the (Aluminum) case is basically a giant radiator, also you get full fan control. It gets hot, blast the fans (both internal and external) and cool it down. Not so much with most (well all) plastic PC Laptops, my Core2 Dell Inspiron was a bastard when it came to fan control & heat transfer, no override whatsoever. It would just heat up to the point of shutdown :fuuuu:
Heat = Death.
