Not bad, but like all Macs, it seems expensive, as compared to a relatively comparable PC.
A good PC is always cheaper, and you get XP or some equivalent Windows product for games, and Linux for everything else. Then, you should have a computer as good or better then the Mac, hopefully. Also, Mac cannot play as many Games as a PC, which is important to a lot of people. While the new iMac is nice, it is still a Mac.
