eMac Support is also in the works, and those are better machines than the mac mini by miles
eMacs aren't really all that much better than MacMinis, they're pretty close. The lack of 50lbs of CRT makes the Mini a better choice IMO, and I have a few eMacs and Minis here.
The eMacs definitely are cheaper when you can find them, though.
edit: have to say, though, my favorites are the G4 iMacs. LCD on a stick in a gumdrop.
