I'm going to go one step further and say tri-corder. That's one device that can do everything and is in everyway superior to what we have now. 2 years tops. The handheld market is currently flying by other technology in terms of development. Current evices have gps, OTA data, voice, fm radio (send and recieve), magnetometer, blue tooth, 802.11 b/g/n. It's only a mater of a few years till it's all as good as it's stand alone couterparts. Agree?
