However, in terms of sheer numbers of working scientists, I would guess I represent far more people than your typical XXX preprint surfer, i.e., the great unwashed masses that electronic publishing is trying to reach. Actually, we of the masses have been already reached. You can even download recent articles, for free. The Nature Web site is quite a bit more hostile. You have to first register.
Many sites have video presentations showing cell dynamics.
In that sense my biological colleagues are far ahead of the stuffy physics community. I work hard in the lab, teach a fair amount, would love to have everybody read my papers and not suffer the sting of rejection or unappreciative referees, and have a family that I want to spend as much time with as possible. Let me consider the problems I see at present, from my perspective. First, at this stage of development you really have to get fairly into your computer in order to properly outfit it with a good web browser, which is nevertheless usually obsolete in six months. You must get ghostscript running, a PostScript printer, Adobe viewer working, a modern TeX suite which will create DVI and PS files, and preferably a copy of Adobe Distiller so you can make your own PDF files.
