Macintosh gets down

I just saw the new Macintosh. Holy smokes! I thought it was a hard drive at first. It's only 2" tall and 6.5"square and the damn thing is more powerfull than my G4! I think I've got it beat on expandibility though. But for $500 you can't beat it. It's a nice little computer for the average user to surf the net and do your taxes on. I just can't get over how small it is. They made the power supply as an external component and it's almost half the size of the computer. I have to wonder about heat and how much of an issue that's going to be. Plus, I can just imagine someone setting their 20" monitor on top of it and hearing "crack!"
