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
Compared to the WebDT366 (@$1600.00 - $1850.00 US) these are still half the cost.
This also assumes that you can get pluto running on the OS (or install other OSs on the device).
They run windows XP.
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.
I had a conversation with a local WebDT366 retailer who was refered to me after contacting DTReasearch who stated that the DT366 (same webpad used by pluto) also only gets about 3 hours of battery life when off the charger.
