Who the hell pays $3k for a computer anymore? I mean c'mon man, you can get something that will do what you want for ~$1,000 now. Nice computers are getting cheaper. Unless you have your heart set on a Mac (which is dumb for the average user) then get something like this. I GUARANTEE this will do anything you want and more, and it's affordable. Gaming, video editing, web surfing, word processing, whatever. This will do all of them at the same time. The only thing you might want is another 1 GB of memory, which would cost you another $80 and even a newb could unscrew the flap on the bottom and slide it in.
