It used to be just because I was interested. Then life got in between and I ditched it a bit, until Microsoft announced that “find anything you ever did”-feature. I installed Ubuntu again after quite a few years and stayed because I finally did not have to spend 3 days to get my video card working “kinda” and I found out my games actually work. No need to use Windows anymore.
If only they would not have to hide these things and could therefore learn how to do them safely.
