Vista for Vurbal, XP for me
And none of the above for 40hz!
Sorry. I couldn't resist. (Although I probably should have. )
Actually I'll have what he's having. It's Windows 7, Windows 8, Linux, or FreeBSD for me. Since playing around with Debian and XFCE on my ancient laptop I can see a day coming when I might cross Windows off the list entirely.
If only I could be that picky with the computers I fix.
