Wait a minute! I'm starting to see potential for real fun with these satnav things! Voice selections could be dowloaded like mobile phone ringtones! You could have Hal, the computer from 2001: A Space Odyssey. It could ask, "What are you doing, Dave?" when you make a wrong turn. Or the voice of Marvin the Paranoid Android! "Enough brainpower to run the entire electrical grid of the United States, and I get to tell you how to get to Krispy Kreme. Why don't you just shoot me instead?" The possibilities are endless!
