I have had and used a computer since 1995. I am now 64 years old and my friends and family call me when something goes wrong with theirs. I can download and back up their data, erase their hard drive, re-install factory defaults, and up-load their data to an almost new computer. I have never had a class in my life, but just like a new quilting pattern.... you choose what you want to learn to do, then learn to do it! Its all up to you!
I have a desk top, lap top, a PDA and a smart phone. And I use them all!
