Well, like I said, this is just a concept configuration. Obviously, the actual design would be much more comfortable than this thing looks. I'm confident that, should this be what Nintendo makes, they'll ensure they make it at least as comfortable as the DSi or DS Lite.
As for the "Dual Screen" name, that's not "official". Straight from Nintendo's website itself:
To our developers, it stands for "Developers' System," since we believe it gives game creators brand new tools which will lead to more innovative games for the world's players.
It can also stand for "Dual Screen."

Key word is CAN. It CAN stand for "dual screen", not that it DOES. With the 3DS, it can now stand for "3D Screen" instead of "Dual Screen".
