My repair business is only small and my customers are mostly home users who are at the lower end of the salary scale, so I spend alot of time trying to get a few more years use out of older PC's without spending much cash. I am hopeful that situation will continue for a few years yet.
However... I find myself more and more giving tuition to people on how to achieve what they want to do on their computers. I used to do this sort of thing as a PR exercise, but now often charge a modest fee for written or prolonged instructions. Once again, I hope that this will be the case for some years to come.
I find that older people are not so interested in the latest tech stuff, they just want to be able to carry on doing what they've always done. Some people don't like change.
