This really seems like a huge Solution in Search of a Problem. The problems he mentions are:<p>1. you have to fumble with your phone to look something up<p>2. you sometimes bump into other people on the street looking at your phone<p>3. screens are bad<p>Are those really big problems? Are they big enough that I need to learn how to interact with an entirely new interface? It's obviously incredible technology, but I just don't see people walking around with these things and talking to them.
