Microsoft's just about everywhere in my house except the Linux box (about to go from SuSe to Ubuntu) and the PDA (Debian). But it's all Win98 plus one Win2K.
If you have children, it has some excellent filtering controls.

Me neither--save for one Win2k qcow (runs in qemu). Personally, I swear on Slackware--my primary machine is running Slack 11, with one three-year old laptop running SLED 10.
Though Ubuntu's good--I'll occasionally fire my copy up (6.06) as a live CD...8^)
