All great points, and there are plenty of examples even among geeks where they get caught at a given point and never progress (I work with a very geeky engineer who for the longest time wouldn't move some perl scripts of his beyond perl 4, even though perl 5 had been around for several years, and the time to rewrite would probably have been minimal).
As a chemistry grad student, a couple of my chem profs were near retirement, and just never picked up email or much beyond MS-DOS. The one has gotten into a lot of that since then, the other one, I'm not sure (no one seems to know what happened to him).radiantmatrix
