This keyboard with a built-in projector does look good for people who need to do a lot of presentations, or for watching video on a large wall in a dark room.
I agree this keyboard sort of reminds me of Typewriters. If the computer make a type writing sound when you press a key, and a typewriter animation showed up on the projected image when you type, it could be more like a typewriter.
The keyboard's seem to be well made like most type writers.
