I'm surprised just how many people here have positive things to say about Windows. Try that on any other Amiga forum. :-D
Ive served time with;
GEOS, WB 1.3 & 3.1, Mac OS 7 thru to OSX, Win 3.1, 95, 98, 2000, XP. Linux: Knoppix, Kubuntu/Ubuntu and DSL and AROS.
Each has its merits and share of frustrations.
I regularly use XP, 2000 and Kubuntu. When something "better" comes along, I'll use that instead.
OS zealotry is absurd.
