My Dad convinced me to try it, as a way to learn more about how computers work (ie without Windows). I installed Ubuntu and didn't like GNOME, but once I saw that all the same programs I used on Windows were still available on Linux, I knew it was worth finding the right distro. I used Linux Mint for awhile because Cinnamon DE was nice, but eventually I needed a more up to date version of something (I can't remember what) so I installed Arch with KDE instead. I've used it ever since.
