I'm against the microsoft corporation! But I think that runnig Vista on a mac is quite a good idea. I think microsoft is stupid. They Build an operating system that's too powerful to be backwards compatible with older computers (only like 2 or 3 years old) I mean the slogan for vista is: The 'WOW' starts now. For us mac users the 'WOW' started SIX FLIPPING YEARS AGO!!
