I want one
I can see a lot of use for something that, for example, let me read a website while streaming a video at the same time, or let me chat and have a comic open on the same device.
Two years ago I couldn't see the need for a tablet (check my posting history, it's true). Then I got a nexus 7. Then a Nexus 10, now I can really see that the extra screen and the multiwindow support would be awesome for my usecase. As it stands I'm often sitting on a bus with nexus 7 in one hand watching a film/tv series/anime and my nexus 4 in the other chatting to some people.
I'd _love_ to have them both in the one device.
Ok, it's not for everyone, I can see that.I've been resisting Samsung devices (well nexus 10 aside), because I like the stock android ui too much. This however has the screen size to let me actually use it with a couple of reasonable sized applications so I can forgive the rest of the Samsung ui (which I generally hate, the app drawer and the settings screens especially. Not keen on Odin either)
