The new apples have the simultaneously best and worst case designs of any current computer manufacturer. Things are seperated and well-cooled, but some featured are in stupidly-hard-to-reach places. On the G5 tower, for example, you have to take out the power supply to get at the motherboard, the motherboard to change out the front power button/usb assembly (!), and must change the entire case if your HD cable fails. Some stuff is well positioned, others are not at all, and I suspect the same design ethos is at work here. It looks cool enough, I'm just still a fan of a true tower design.
