I became an OS/2Warp 3 user just a few months before Micro$oft released Windows95. I continued to use Warp 3 and then later Warp 4 for the rest of the decade, or whenever it was that IBM gave up on it. If there ever were a 64 bit version, that is probably what I'd be using today. OS/2Warp had so many firsts, unfortunately the best don't always win.It wasn't that I disliked the kernel, I just didn't see it as important (to me anyway).
It didn't worry me if I was using GNU/linux (GNU's not Unix) or BSD (an actual unix), they both worked for me, and given my primary OS was OS/2 at the time, I was really just playing with the *nix as it was on the newish-device. (Debian came on the dell; I installed a BSD on another desktop; being on a desktop meant it had a real IBM model M keyboard which is a huge ++). I continued to play/use both for a long time, but was finding GNU/Linux easier to work out (despite it's keyboard; eg. networking, sound, much later on SaMBa etc); which would often cause me to learn enough to subsequently get it working in BSD later. Years later I dropped any play with BSD as GNU/Linux I found much easier.
If you need an answer (dislike & kernel); on that really old Debian, I would have liked to have sound & networking.. but I had a script that would `rmmod` one & `insmod` the other.. but I took that as a limitation of RAM (32MB at that time in the dell debian laptop). Later kernels didn't have that limitation though; but that didn't worry me either; I had my sony walkman (with my self-mixed cassettes for music!)
