projeckter camera is waste ?

I think it's a simple, yet creative idea :) For example, you could go Trekking, take a lot of photographs, and when you return, instead of loading them onto the Computer, you could just put it up on the nice, big, wall opposite the Sofa set! That way, everyone gets to see a big and clear image :) It's a good feature :P

It's just an extra feature. Why do you say it is a waste? Maybe the way your pictures were taken are so ugly you can't show it. Have a nice day.
