I have 1 big issue with this tablet. I think it's safe to assume it will be running the integrated graphics on the i7 proccesor (which are good), but what about in 2 or 3 years? You can't really upgrade the hardware in this tablet as time passes on, and we know how fast the graphical requirements for games increase as time goes on-wards. Hell, in even a year or so, this tablet will have considerable trouble running any graphic-intensive game at reasonably settings. This means that people will have to ask themselves this, "Is $1000 worth possibly 1-2 years use?".
However, I do appreciate the innovation. I hope that other companies borrow from this idea to produce a product that can address such a problem.
