I think this defeats the purpose of the netbook in the first place- small, lightweight, used for internet access and similar sorts of behaviors. It's the kind of thing meant to be carried when traipsing about. Perhaps a netbook and a separate, small, DVD player. True, it will be one more thing to carry on the plane, but when bopping around town and wanting the small netbook for wifi or broadband access, the DVD player stays at home.

Cheers.
