I've been using computers since '86. Was a huge fan of DOS back in the day. Didn't like Windows 95 much, but eventually installed it in '98. That didn't last too long - around April or March '09 I figured I should try out Linux. First I went with slack, which didn't work out for me. I seem to remember that I first went for Debian, and then later on for SuSE for some years. Then it was a series of SuSE->Mandrake->SuSE->Ubuntu.
I had to fiddle a bit with Win2000 as a window desktop, and then later fiddle a bit with I think it was Win2000 or was it 2003(?) on a few servers. The main bulk of the servers were Linux and Solaris.
I very seldomly had to help out some XP users. I've barely touched Vista, and I don't think I've seen more than one computer w/Win7 ever. Anything newer than that and I haven't seen it at all.
Now; why won't I touch Windows? Quite simple - I have no clue how to do stuff with them. Family has been converted to Linux (and some Mac) years ago. I wouldn't know a thing about how to get stuff done. I've heard rumors that powershell is kind of cool - but I'm familiar with bash that I guess my only option for windows would've been cygwin - but that feels kind of bastardized instead of just having a desktop I immediately feel familiar with.
I'm pretty sure windows is quite cool for those who knows how to use it, but it ain't me.
