I use linux only at home, linux only at work, and don't let anyone do anything with my computers (in particular, the support guys at work).
More: I bought a N800 because it's linux (I would have bought a smartphone otherwise). I wanted all my scripts and programs to work on the tablet, want to use mutt, vi, ssh, rsync, etc.
Personally, I am a Linux geek. I have between 14 and 20 Linux boxes at home (both bare metal and virtual), and I am a Unix/Linux sysadmin by trade.
Same here ;-) Running Linux[1] mostly[2] everywhere[3], ever since a fateful day in 1993 when I went through a ~50 floppy SLS[4] installation and never looked back.
[1] No particular relig^Wdistro, currently a mix of Fedora/Centos/Debian/Ubuntu boxen[5] and various "embedded" variants.
[2] Modulo a few OpenBSD firewalls here and there.
[3] Even in places I'd never expect to find it. You know "world domination, fast" has happened when you receive a GPL notice with your TV.
[4] 386BSD also sounded good at the time but it just wouldn't fit in my box.
[5] Is it a bad sign when you're running out of IP addresses on a /27? And if that's just your home LAN?
Programming Fortran in Mass. in 1970. Worked with Unix on Dummy Terminals from about 1976 appox.. Then consulting for financial institutions then on to PCs with 300 baud modem to Unix Mainframes... and you can guess the rest.
