It's good, there's no doubt and serves iTunes users well. Soon my xbox will take care of my media centre woes. I wanted a nice small PC/laptop capable of 1080p without jerking, to mount behind my TV and run XBMC or Boxee (which is based on XBMC), however the xbox is getting iPlayer, 4OD etc and already streams my music and movies from the file server...
If I were an iTunes user, I'd probably have one. Cheap enough!
