Not all that useful for the average person though. What would really sell among the non-scientists of the world would be something that could determine the nearby air quality. A thermal sensor giving images like this would also be useful to homeowners - the thermal sensor wouldn't have to be all that impressive, just enough to tell where certain leaks are letting in hot or cold air into a house.
Wikipedia has a few examples of some other primitive tricorders here, but none of them are quite snazzy or convenient enough to have become popular - having to buy a completely new device usually just isn't worth it. Create one by connecting to an existing cellphone though, and you have something worth developing.
