Using one here at work with http://www.screenlyapp.com to drive an HDMI display on a wall, showing phone call queue statistics to our CS agents.

The fun thing is that we're powering it off a USB port on the HDMI display so all it needs is the ethernet connection.

Unfortunately for compliance reasons we've no WiFi in that area otherwise it would be a totally self contained unit.

I have it with the latest openelec. sometimes I use raspbian. works without any problem.

I have several of these guys. Some with the PiFace board for IO (8 input and 8 outputs, two with relays).
Have implemented several projects at work using these.
The Pi seems to run forever without freezing up. I'm very happy with the performance.

i got one, sitting on my shelf collecting dust atm, but it looks good, especially if they can get VLC to work with openmax
