Promising first steps....
No, I don't want to do video-editing on a mobile phone, but imagine the convenience of a scaled-up version in a system otherwise no more powerful than an eeePC or Aspire (or perhaps even a OneT!)
Surely it's trying to keep the battery running long enough on your overheating MacBook Pro or shiny little Vaio that stops the average small video business being able to do on-the-spot editing. So a low-power option is very appealling. Hell, surely even the Beeb would want them as a backup for their enormous outside production units.
