Slackware was mine too - all it took was a box of floppy disks and tens of hours of downloading and installing! It was great though, something so different. But it was just a toy, and I went back to DOS/Windows on PC - mainly for the games and hardware support (Voodoo!)
A year or so later I spent a lot of time playing with Solaris and VAX/VMS at University and really developed a love for the command-line and UNIX environment. It was that which led me to my first job (with HP-UX) and my second (Debian/Yellow Dog). From then on I used it at home a lot more. Now I use Windows for games/gamedev, and Ubuntu for everything else (desktop, laptop, servers).
But it’s amazing how far things have come in some respects, but how some things have regressed over those 20 years - window managers/themes never reached the heights I envisioned in the Enlightenment hay day, session management/restoration/remoting seems to have been eroded away, virtual desktops/window management/tiling regressed and became fractured, the wonder of Compiz didn’t really move things in an interesting way, and I felt sure Quicksilver (for MacOS) was the future of launcher, but it’s not really been taken up - though the Expose feature is an excellent essential part of Gnome now (Activities)!
In some ways I think Linux has lost that “wow factor” that we used to have with all those cool features - but it is much more rock-solid and professional now! I use it more now than I ever have.
