It is TSA compliant and fits within carry-on size dimensions, so you don't have to check it in your luggage. That's yet another selling point for it. Got a 4 hour layover/delay in Chicago because of bad weather? No problem, just whip it out, open it, plug it in (plenty of outlets at the airport), and spend your layover/delay playing xbox. The 360 power brick, cables, and two controllers all fit within its interior (bags beside xbox hold accessories) with room to spare for a couple games. Then close it and take it with you onto the plane when it's time to board.
