It's almost like a mini-console. Did anyone make something interesting/useful for the Pi yet, or is it purely a toy? I'm imagining it'd be a nice way to keep a server running in a low cost from-home fashion.
I was trying to use it as a media server, but the software just isn't there yet. Linux versions of Spotify are flakey and don't play all tracks back properly, and although there's a build of XBMC for it, I couldn't actually persuade it to play any media.
I'm toying with the idea of hooking a few together for a render farm, as soon as I figure out what to render.
 Insert usual rant about linux sound here
