Sabredog, I think you missed my point about why the big box is endangered. Large display technology has to become portable. I used examples of heads-up, other light projection, and direct mental communication.

With my desktop publishing (Quark), Photoshop, and Lightwave uses I don't want to give up my dual-monitor real estate either.

But the processing power we require is getting smaller and more energy efficient. There is a Moore's Law-like computing power-per-watt trend that goes all the way back to the 1960's that suggests we could be there in about five years (meaning a battery that can power today's typical PC processing). Our wireless protocols continue to get more power efficient as well. Why have a big box when a smartphone sized box will do the work? I get the display (output) and data (input) issues but I see ways to solve those that don't require physical monitors and physical keyboards, perhaps coming a bit later than the powerful-PC-in-our-hands.
