I’d actually take the idea even a step further. Sooner or later I want an analog watch that carries a powerful computer. That’s all I want to carry around. Monitor, keyboard and mouse stay at the office and connect to my watch when I sit down at the office table.
(Note: I don’t want to fiddle around on the tiny smartwatch screen, hence a classic analog watch. If anything, then retina projections and a conversational interface.)
