Well all I see here is bashing of macbooks
I don't own a MacBook Pro, but I'm a proud owner of 13" late-2008 Macbook that has been updated only with new bigger and faster HDD and had Ram expanded from 2 to 4GB.
To the guy that gets from WOW 10 fps I can only say "Update your drivers" and you'll get more, cuz I get ~30fps (not while raiding though). I can even play Diablo III, Dragon Age Origins and some other not so new games (GeForce 9400M wasn't built for games). Coolers can be manually accelerated to max so temps don't go past 75C.
And as far as Windows performance goes, it's great I have good boot time (which can be improved further with SSD), I have good performance on day-to-day tasks and no problems with errors. And what's best is big trackpad compared to normal notebooks that works great (although on MACOSX it works even better).
And as far as Drivers go, I'm yet to have a problem. So I think that all who complain have a problem not with their MBP's or MB's, but with connection between Macbook and chair
