In my opinion they arent even worth it at 1/4th of the prices shown there, I used to work with em, about a year ago on my last school (networking mostly) and I have no clue what they can do that a pc can't do. A pc can do allot more infact, first off all I've heard people say that the GUI is supposed to look better, they are right (when comparing a stock installation). But you can get a XP desktop to look better anyway so there's not really a point in that. Anyway, in performance, I really don't know allot about the mhz on macs, but IMO they are not really slow. I seen it run a game once, believe it was some disney game. It ran ok not much difference with a pc. These are the things that I don't like at all about em: gotta get all special "MAC OS" software, for anything such as games, gfx editing, sound editing, EVERYTHING! , the locking up sucks a** too, the commercials that claim that MAC's are better then pc's n s*** like that.., special packing tools (like zip on a pc) they have something different (not sure what it's called anymore), also the hardware like some of the mp3 players only work on MAC-OS. Think that's about it. The only thing that I like about some of em that they look pretty fresh. Don't waste your money on a classroom toy like that!
