Just one thing: there's absolutely no way that the speed of Mac processors is the double of their PC counterparts. (And since a Mac is also a personal computer ...) The way they do things in Mac and PC, there's even no way to directly compare the things, except in the task comparison tests. But that's something else. The reason PC fanatics won't even consider a Mac is not just the price (at least four PCs for that kind of money) but als the closed architecture. the situation is better about that than it used to be, but it's still closed and you cannot mix and match cheaper/better parts much.
