Working PCs only, I imagine? In that case:
Work PC: XP
Main PC: XP
Son's PC: XP
Daughter's PC: XP
Wife's Laptop: XP
Work Laptop: XP
My Laptop: XP
Son's Laptop: Win95
Cellphone: Win Mobile
Old Kids PC: XP
Wife's old Laptop: Win98
My old PC: Dos 6.2, thanks to my dad deleting the OS in his botched attempt to delete his files when he gave it back to me for the kids to use. To my chagrin, I discovered I only have win95 and win98 "update" disks, which means I'd have to install win 3.1, upgrade to 95 (both via floppy disk), which only then would let me upgrade that to 98. It's a Pentium 100MHz with 32mb RAM and was my first "real" PC in college, so has a lot of sentimental value. I installed DOS on it so I could troubleshoot, but even the 400MHz machine the were using was painful, so I just bought the kids new computers for christmas instead.
...Wow, looking back up at that list, I've got a lot of computers, lol
