Got notice from DirecTV of a new system (Sat-Go). Combines a DirecTV receiver, antenna and TV in a portable unit, and looks to be the size of a laptop. Have no idea if it can be used while in motion.

Personally, I'm not sure I even like the idea that I have a DVD player in my SMB, as I'm trying to get away from those things while camping, but with a young son, I'll never say never.
