I kind of laugh at the people in this thread thinking that this is an underpowered CPU. Try doing some research on it before commenting please.
It's been noted to compete in performance along side an Athlon 3000+, and has Hyper-threading. They also have a dual-core version coming. Compare that with what VIA and the like are offering in the same size package, and you have a platform with stellar performance, amazing low power compumtion, and the ability for an amazing media appliance.
For $80, I may be jumping on a few of these for either folding or server duty.
On a side note, I had a carputer running geexbox for over a year with no problems. Matx system with a 600mhz duron, 20gig pata drive, and a lappy dvd drive. You don't need 3Ghz of power to play a movie.
