The Superbook: Turn your smartphone into a laptop for $99 (kickstarter.com)

Well not the first of its kind. Unclear how this one exactly works. Is it Micro HDMI over the USB-OTG or just a socket over usb and another SoC in the Flapbook?

EDIT: Ah displaylink, I can see it getting choppy with older phones.

Wish this existed for iPhone.
