Just picked up a Surface Pro 4 and flew with it. It was extremely awkward to use that and the Arc mouse on the economy tray table on my BOS-LAX flight. It also ran down on power pretty quickly playing video games. No power outlet in economy (or 1st) on AA.

Has anybody found something to strap the thing to the back of a seat above the tray table? I think it would work a lot better if I wasn't hogging up the tray table with it (I use it with the keyboard).

Nothing to be done about sucking up power when playing video games unfortunately.
