Is the Single-Function Device Doomed?
I get the value proposition--how useful and space-efficient it is to own a single device that can function as a phone, a messaging appliance, a browser, a camera, a videocam, an e-reader, an MP3 player, a GPS unit, a tape recorder, a stopwatch, and so on. Today's smartphone is the last word in convergence devices, the electronic equivalent of the Swiss Army Knife before you've misplaced the tweezers and toothpick.
