Very cool. It may be worth pointing out to those who love the idea of more screen estate in your laptop bag but are not aware of existing options that you can already do this by packing one or more portable screens.

Less street cred than the featured gizmo but available now and likely a heck of a lot cheaper.

I currently have a portable screen, keyboard, flat mouse and foldable laptop riser with my laptop in it's bag - though haven't used them altogether in public for fear of being "that guy".
