I believe someday we will have "wearable" computing but I don't see it in the form of a bulky wristwatch or even that "Google Glass" - which has the fashion sense of a bicycle helmet. I believe fashion plays a big role in the success of technology products. Apple (Steve Jobs and Jonathon Ives) probably tapped into that better than anybody else as their products look "cool" to tote around.
Not so with the Segway and the obligatory bicycle helmet which combine to create a double feature of dorkiness that cannot easily be undone. For example, the kid below is not going to pick up that girl and he'll be home tonight binge-watching some lame sitcom all by his lonesome self.
That’s George Michael Bluth!
