... a lot of scrolling to view a simple spreadsheet and I haven't tried any CAD program as yet since I think it would be a waste of time. I know that we used to do everything on a 640 x 480 screen some years ago but I do remember running Autosketch on such a screen, and it wasn't easy. What I possibly see in the future is the small portable computer (in whatever guise) which allows the owner to have easy portability for all the functions that the mobile generation want- like email, facebook, Net surfing, tweeting, etc., but can be docked at home to a base which hooks you up to a large screen and, possibly, large capacity disk drives. We have had that facility for some years now with laptops and netbooks, but the advances in chip technology might let a much smaller Iphone size appliance have the processor power to run the high end applications at home so that people only need to have one computer to do all their tasks.
