@stefano Hi I'm hyc. I only used Windows on my work PC 1995-1999 because that's how that particular company did things. Prior to that I did BSDish kernel hacking on Suns, Vaxes, and Alliant FX. At home I used Atari STs from ~1987 on. In 1999 when we founded Symas I ran a SparcStation 20 at home along with a Linux PC but my primary machine was still the Atari TT I'd been using since 1994.

I've had to run Windows on VMs when porting/testing stuff, but it's never been my primary system.
