What is a handheld device?
What is it? Well, obviously it’s something you can hold in your hand. So under that broad definition we might have to include the nozzle of a gas pump as a handheld device. OK, then maybe we should add the word portable to it; what is a portable handheld device? A can opener is a portable handheld device. OK, add another word, electronic (as distinctly differentiated from “electrical”). That would include everything from an FM radio to a garage door opener. OK, add “with a display.” Now we can include everything from a watch, a remote crane controller, to a spectrum analyzer. How about adding, “with a keyboard?” That narrows us down to Gameboys, phones, PDAs, Harmony TV remote controllers, laptops, and data collection terminals.
