They won't switch, Bill, because it takes the initial effort of...

1. thinking about something new
2. finding out about it
3. then doing it
4. thus initiating change! (ouch!)

They'd rather not be bothered with all that. They'd much prefer to just keep doing what they're already doing.

This is the reason why our old dog would not use the gently sloping ramp I thoughtfully built for him because he was having great difficulty climbing the steps. It was a new idea! New ideas require changing existing habits! He would not use the ramp. Nothing would persuade him to. He would rather die than use that ramp. It still stands there...unused. The dog died some time ago.

That's what people are like too. ;-) The problem is definitely psychological, not technical. It's mental inertia, combined with fear of change. I don't mean to suggest that I'm immune to it, either! I'm not. I have not bothered to learn a whole bunch of new tech stuff that might be good to know...simply because I can't be bothered to at this point. I don't care enough about it to bother.

If someone were there to demonstrate it and help me learn it, though, then the chances of my doing so would increase tenfold! So it is isolation that is part of the problem.
