Not had a proper watch of the videos yet, but this looks cool. A combined 360 and One in a single portable device: http://www.edsjunk.net/wordpress/?p=277
I don't get the appeal of these "portable" systems. Especially until the Xbox One gets a slim redesign (which almost certainly will happen), the thing is an enormous bulky mess. Same with the laptop versions of PS3s and 360s that I've seen. The only one I could see would be a Wii or Wii U for non motion games.
It was cool when BenHeck was originally at it with the laptops, but now they don't even seem practical unless you are stationed in a 3rd world country or you are constantly at LAN parties.
