I thought I would see more spandex and maybe a few jet packs in the future.


It seems their future involves carrying around a brick like device. I'm thinkin' the brick like devices would be stationary but plentiful. I'm hopin' that some universal standard could be developed so that all one needs is a device like that watch.
It would transmit this standard identifier that would allow the wearer to interact with the brick in his car, on the bus, at a kiosk, on a restaurant table... seamlessly using a personal GUI and personal data served up via a networked connection.

The dude with the watch walks away after manipulating his personal data and the connection is terminated. Then someone else with a watch walks up , gets in the car, or sits at the table and ZAP... up pops his personal GUI and data.

There would still be times when you would need your personal brick, but those times would diminish as more and more stationary bricks are deployed.
