@Tom 13 RE "but not so much for your average punter."
Yes, this is in fact a real problem that I in my opinion is rooted in the education system. We are the last generation that have grown up with people for whom the pc is some "new thing". When I was a very little lad a much loved friend of our family was a very elderly gentleman for whom the telephone was something he hated and feared despite the fact that he was a chap of considerable intellect. This "technophobia" is something we have to address - though how we tackle it is something that I do any good suggestions for.
