That sounds like the existing Magic Keyboard for the current iPad airs and pros, can you explain the difference a bit more?
it definitely looks cool (i could see the design having been inspired by the OG Mac and 20th Anniversary Mac) but works best on a stable surface; plus if you want to use it purely as a tablet, you're left with a big clunky keyboard case to deal with.
the idea of a laptop/tablet combo is cool but i haven't seen the concept executed very successfully from either starting point.
