As the user of a mobile workstation, most of the time its stuck in a docking station on my desk and hooked up to a 24" screen, but I do need to be able to take it with me when I'm not at home/office. The idea of a box like this appeals. If it could be a tablet when I'm just wanting to gaze at the Interweb or read emails etc. Then be able to use it as a real laptop when I need to type more than a few lines, and to be able to use it with a real screen, or preferably 2 real screens when I'm at base, but to be able to take my environment and data all with me where ever I go. This sounds great.
In practice though, I wonder how compromised it will be. It sounds heavy. The screen is the pathetic HD (lol) spec.
Perhaps if I could have a Window's live image, like any decent Linux distro can do, then I wouldn't need to worry about a flexible piece of HW. I could just have my little "SSD cartridge" perhaps 4"x2"x0.3" and weighing in at maybe 2or3 oz and I could then just easily switch between different dedicated bits of HW without the inevitable compromises. Just plug in where ever you go and run your own "home" environment.
Sadly it ain't going to happen, so something like this might be the best the world will offer.
