Interest in alternative operating systems. I'm old so I got into it back when Windows 95 had just come out. Mandrake was my first distro, but I was also weirdly interested in BeOS and OS/2 Warp.
I think many try to some extent, but we don't exactly leave a lot of room to manoeuvre. Classrooms don't seem to work without substantial conformity, bills have to be paid, employers catered to, and even just plain social pressure to not stray too far off the beaten path.
