My computer experiences started with MacOS at the age of 7 (Mhh, MacPlus with 9" b&w screen, 20MB HD, 512kb RAM and 800k Floppy in a cute machine) plus a C64, mainly for robotics (I had lots of the "Fischertechnik" construction parts (like Lego, but a thousand times better) from my father, including the C64-Interface), years later I switched to windows, because of the incredibly high prices of Apple Hardware, and after some long painful years of fiddling with Redmonds 98, 2000 and XP, I finally got the guts and started learning linux.
I collected my first linux-experiences with SuSe (German distro, very GUI) about two years ago, but I was not really happy, just because it was too much like windows. I also tried RedHat, same problem. Then I found out about Gentoo and tried to compile it from stage 1 on a 300Mhz machine. After 5 days of watching gcc output, I lost my patience, formated the HD and installed Slackware linux.
And that is the distro I use since then. It was REALLY hard at first, I had no one around me with any linux-experience, and it took me days to get the simplest things working (like Mouse, CD-Rom etc), but it was worth it. I learned really a lot about linux in that time, because Slackware has no graphical installer, no easy setup-tools, you have to do everything by hand in config-files. It is known as the most "unix-like" distribution out there.
Now it runs on my desktop, my laptop and the server for my co-inhabitants. I am absolutly happy with it. But I could imagine switching back to Gentoo one day. Maybe on a faster machine and not everything from stage one. I even use linux on my pda, a Sharp Zaurus C760 with pdaXrom on it. I use Ion as window-manager which is very different approach to window-managing, but i think its pretty useful and i like it if no one else can use my computers
Makes me feel special.
