For me the killer app will be able to use this it as a remote for music being streamed from my desktop. There are a good few ways of getting the music around the house now, but short of the Sonos package nothing to be able to easily select what's playing. My dream is for a iTunes-remote running on the 770 in the lounge.

Am I missing something but why put a P2P app on a tablet, there majority of the files used will be streamed over a WLAN?
