This is interesting and off-putting at the same time. I'm a writer who likes vintage tech as well as low-tech solutions. I write a lot by hand with pen-and-paper, so I appreciate techniques that force you to stop and think as you go along. But that said, did we really need to pay extra ($500 worth) for a gadget that takes away Twitter and email? And arrow keys? It seems like you can get all those features from a ball-point pen, although I suppose not everyone prefers the feel of a pen over the feel of a nice keyboard.
In the end, though, it is a pretty machine. I am shallow enough to appreciate it for its appearance at any rate.
