I only have one question - battery life? This is the only thing that matters if it becomes a hinderance, and the only thing that doesn't matter if it's not.
We have the same question, they did not mention anything about battery life. I'm not sure about the video, I don't have my sound card installed on my office workstation. If this could last as 5 hrs for an Ubuntu Desktop, I'll buy one.
We assume it will be plugged into AC when in desktop mode.
