"The silly/telling moment came when I caught myself, for the umpteenth time, trying to tap the screen of a non-touch phone. Go on, you try it - use a device like the Nokia 5800 or iPhone for a few days and then go back to something like the Nokia N86 or E71. It's not a criticism of the latter's functionality, but I BET, I absolutely WAGER that at some point you'll see something on the screen and find yourself tapping it and wondering, just for a second, why nothing's happening!"
