Who needs Windows updates...
For all that The Reg FOSS desk doesn't use Windows much any more...
My best guess if that your staff is quite content with MS-DOSFreeDOS and runs WordPerfect 4.2. That would make for real productivity where all the distractions have been eliminated. All those pesky Internet distractions, who needs those.
And I'm almost sure you are running AIX on the rest of your systems with your PCs as terminals. The good backend publishing system for all your publishing needs must be running some established *nix variant. Sure, you have experimented with that new kid on the block, whatayacallit, Linux, but that is not for a serious publishing outfit as you have there, I guess.
The only place you'd be left running Windows is on your mobile phones. These rock solid devices will survive a meteoroid impact and tsunami hell with battery and screen to spare! Probably also used as a smart terminal for your emulated DOS sessions on the AIX box running WordPerfect. Who guessed you could run remote applications (over IPX, of course).
