This is why I want one. I like to carry a tablet to read books and take notes at the same time (Android multitasking + a bluetooth keyboard) in places (planes mostly) where my full laptop is a bit too big/too much overhead/doesn't have enough battery. Unfortunately, that adds weight, and it's another thing to keep charged. These seem like a great solution - if perhaps a little small for now.

Yeah, I'm a bit surprised by the comments like "who would want this". A phone that you can unfold into a tablet when you want more screen? It's awesome. Now I don't want this particular device, or the Samsung one, because the tech isn't quite there yet, but the second or third gen _could_ be amazing.
