I don't, and I'm a PC (I do own a Mac but it's not what I use most).
Think yourself lucky you didn't experience Windows 1.0. I did. At least Windows 2.0 allowed overlapping windows.
Anyway, my computing history is frightening. These are the ones I can recall using, and I'm sure I've forgotten some...
