>>If the user is on the move as was this tech, they have terrific power- but for a comparatively stationary user, as most users are in today's world, the big screen and big keyboard will be hard to replace I think.

I can provide other examples- for example, many digital xrays need very large high-res screens. IMHO the key is to focus on the requirement, not the current best solution, which today may be a very big expensive CRT in some cases. But I have great faith in my fellow human beings' ability to come up with better ways we never imagined, with "screen" reduced to a label just as "horse power" is when we talk about personal transport. ;-)

FWIW, while you and I can come up with countless examples, most people our there use their machine for email, browsing, content creation using one of a small number of standard options and not much else that can't be handled by a phone. People are going to develop expectations that vendors are going to want to meet. Also FWIW, recently I was looking at the Intel D525 and i3 2100T and the AMD E350: these tiny low-power devices are INTENDED to drive large screens not just with content but with bluray movies. One of them can fit in my pocket. OK it's a trickshot, but things keep getting smaller and screen manufacturers have already shown huge screens that fold like paper, which is just one possibility to do away with a fixed screen.
