For general-purpose application, it is very slow (cpu rates at 1.3). It was designed for media playing though. If you are not in a hurry (I mean "days"), I do have iTunes and airport express. I can install iTunes to see how it goes (I have 40000+ tracks, so it will be quite a stress test). But when I have time...
For my application, it is performing amazingly well (a bit thanks to Win7). If not in "standby", touching the screen and then a button for my remote is instantaneous. When in standby, it takes only three seconds to wake up and reconnect to my server application.
