I was waiting for the release of these to see exactly where they would be positioned. I had heard rumours that they would be more in the 200-500 dollar range rather than 700-1000+ range which they seem to be in.
At that price they are too expensive IMO for just an orbiter but they are probably sufficiently spec'd to make a mobile Media Director. Currently the MD is tied pretty closely to a room but maybe this can change by having a similar device to MD but that is Mobile (just like the mobile orbiters are implementing an orbiter). This also assumes that you can get pluto running on the OS (or install other OSs on the device). Be interesting to see if they can Net Boot.
The battery life is a bit of a concern though. They are stated at only having 2-3 hours which is probably not long enough.
It would be interesting to play with one though.
