Not a laptop
I think it would rather tricky to balance this beast on your lap, so call it a protable desktop computer instead.
Also, I think the dimensions (at least width and breadth) of portable computers shouldn't extend much past the dimensions of the screen. Why would I want a larger footprint (when closed) if I don't get any usable real estate for this? There is plenty of empty space above they keyboard, so if you want a slanted keyboard, make it bend there instead.
Presumably, the "stand" is used to hold most of the electronics so nothing needs to be tucked under the keyboard or behind the screen, so you can reduce the thickness. But I don't really get this urge to make things as thin as possible. I would rather have less weight than less thickness.
