This thought just occurred to me the other day – both my parents are Linux users! My father is mainly an office user. He uses the computer for checking emails, typing documents and preparing spreadsheets. My mother mainly uses the computer for playing games. Regardless, both of them have no complaints with using Linux as the OS simply because it does the job that it is supposed to do, which is more than I can say for some others.
That got me thinking that if grandpa/grandma are capable of doing this, what is stopping anyone else? My parents had no real legacy tied to Windows. While both started using computers with Windows, the things that they were trying to do had absolutely nothing to do with Windows. Of course, having me as their son is useful too.
However, I have to say that I did not have to teach them much. All I taught them to do was where to find the applications that they needed, and how to shut down the machine. That was literally it. I did not have to teach my mother how to play the multitude of games that came with KDE built in. Neither did I have to teach my father how to use OpenOffice. He was already used to using Microsoft Office before this and found the switch pretty simple. I did not even need to set up the printer for them.
All hail the grandma/grandpa OS, the geriatric OS, Linux!
