I see what you're saying, but it has gone down fine so far. My dad is completely computer-illiterate, every phone/computer he uses seems like it was found in an alien spacecraft to him, so changing from Windows to Linux doesn't make any difference to him. He just needs to be able to click the Chrome icon and then click the YouTube favorite button or the Hotmail favorite button.

My mom worked way back in the day for a corpo that used DOS systems, so she actually has remained slightly computer savvy. She was worried about the change until I showed her that the Spotify app worked perfectly, she could read her emails, open Word documents, and print stuff.

I also explained that the computer would run faster and would be safer for them to use because the malware that effects Windows doesn't effect Linux, and that made sense to her.

If she had insisted I keep them on Windows, I would have. But she was just concerned that nothing would work the same and she would have to become some techie to figure it out. Once I addressed those concerns, she was alright with switching.
