I can already do all that traditional stuff on a macbook or ipad, and "have a screen anywhere", and those things are more portable because I can just sit it on the table instead of having to untangle A CABLE from my clothing and then find somewhere to place a headset that doesnt sit flat like an ipad or macbook.

Then there's the fact that ipads and macbooks have keyboards.

With no killer app, this is a boondoggle, I think.
