The last microsoft "operating system" I used was DOS 3.3. For years, I used DR-DOS/OPENDOS/etc, with Desqview. I got an early copy of Yggstrdill (please correct my spelling), but never got it to work. I've fiddled with RedHat (4 and 5, I think), Slack, Debian (Potato was my earliest I think), Caldera OpenLinux (I still use a Caldera server with kernel 2.0.33 dated Jan 1998). Mostly now I use Ubuntu/Debian 6.10. Since Potato, I been almost exclusively with Debian and children.
