We've posted quite a few concepts on UltraLinx but this one is just ridiculous. Most phone concepts are realistic and could actually be done in the real world, I doubt this one will ever even surface.
This iPhone comes apart at the top and bottom to reveal a virtual keyboard and a projector. What you then get is a keyboard and trackpad for use with the full OS X.
This concept is utterly ridiculous will most likely never surface. But credit to the guy who put it together and was wacky enough to think up something like this.
