Ok so these have been cropping up all over the place and have dated right back to the old PDA days – Checkout the mini projector that converts any flat surface into a touche screen
Although never actually using one for any long periods of time I do have my doubts about these – 1) using a hard flat surface to tap away at keys for example whilst writing an email does get very uncomfortable and annoying – and 2) the problem is when ever you see the promo videos it tends to ALWAYS show them in a dark or fairly dark room and never a well lit office or sunny day – the reason being its virtually impossible to see the projected image under these conditions.
Other than that I think its a great concept and good gimick.
