That's what I'd imagine too, but thinking it through... the keyboard on this thing is super lame. The lack of a Delete key alone would piss me off if trying to do any real writing.
I don't see a "travel" use case that couldn't be served by a MacBook Air (with the Karabiner utility to fix ITS insufferable lack of a Delete key).
To me this thing is for very limited technical scenarios, for example as a video signal generator or some kind of analysis or testing device to be used in the field. It might be pretty cool for something like that. Or for mobile hacking.
