Mac mini is definitely cool. I last owned a Mac in college and its portability and durability were wonderful. Granted, having a tiny (what was it, 10"?) monochrome screen wasn't all that great, but it was excellent for moving around when you changed dorms every year, came home for the summer, etc. I've used and owned PCs exclusively ever since, though, primarily for their price/performance advantage, although I've also enjoyed the larger software libraries of the Windows world. Of late, though, I've been really impressed with the price/performance ratio and stellar design of the new iBooks. The form factor of this new mini blows even the smallest fanless Shuttle PC form factors I've seen out of the water. This means nothing but goodness for both Mac and PC users, as PC designers begin to take cues from Apple's design leadership. I can't help but think how much $$$ Dell could save on shipping and warehousing if it were able to reduce the bulk and weight of its desktop PCs to this size. Granted, manufacturing and component costs would almost certainly rise significantly.
