Do you recall years ago we saw this projection keyboard being showed off, often they were connected to handheld devices without a real keyboard.  They would project a keyboard to a surface (eg. table) and you could they type on it by placing your finger where the corresponding letters were projected!?

Well the idea never really hit the shelf’s from what I could tell, at least I never saw a retail version – that is till now…  ok ok, I admit I did not really look for one so they may have existed for some time, but now I came across one it seemed worth mentioning.
