One of the things Dr. Teller mentioned in the machine he's developing is the ability to read signs at a distance. I could really use that. I work in midtown Manhattan, and I find the GPS pretty unreliable there, because of all the tall buildings. Even here in Jersey, it only gets me close to something. There are still at least 2 or 3 doors to choose from. I think it would be great to be able to read an address or sign. I can imagine walking through a mall and being able to read store signs, or walk through an airport and read gates, or the sign saying Concourse C and an arrow, or even my perennial favorite, the sign for the ladies' restroom. Then, if I could use the same device to walk into a store and read the price tag on an item I'm interested in ... well, sign me up! Being able to read at a distance or close up is something I could really use.
