Andrew Turnbull still uses Windows 95. Hardcore.
You know, in some ways Windows 95 was the best Windows ever. Windows XP has it's good points as well.
But for me, it's Linux forever. Well, some kind of GPLed Unix/Plan9/Hurd something forever at least.
But Emacs forever!
I'll be 90 years old, still working in Emacs, you can bet on that.
