Wow. You people clearly have no clue of what a Mac is capable of doing. I got a Mac OSX Leopard for Christmas last year and it is AMAZING! It has absolutely no problems at all except that some games are only for PC, but the only game that i ever play on here is Blockland, so that doesn't even apply to me. It also even came with all of these amazing programs for no extra charge! Like Garageband (only on Mac), iMovie, iDVD, iPhoto, and Potobooth, just to name a few. It also has a nice, high quality built-in webcam, it runs much, much smoother and faster, and is overall just a lot easier to use.
Mac = Epic Win
PC = Epic Fail
