If we're talking dreams, I want a set of devices that aren't synced - I want them to be the one device.

I'd like some form of main computer cube that can fit in a pocket or backpack, and a load of little devices that communicate with it. All of the other devices on me would link to the computer.

The watch on my wrist would show the time, date, or anything else I want, though of course limited by it's smaller screen, but then it's only supposed to show updates.
A tablet-like device would be the main way of communicating with it. A range of sizes depending on personal preferences.
You walk within range of your monitor or tv and you can use the full screen.
