And Macs. I agree. To quote a friend, "your momma dresses you funny, and
you need a mouse to delete files!"

Yeah, and 3.0 broke a number of things that were in 1.0 and 2.0; one of
the biggest mistakes M$ ever made was not introducing in 3.0 at least
foreground/background multitasking (you couldn't print and do anything
else!) and virtual memory. If they'd done that then, WinDoze wouldn't have
been the disaster it became with the 95 line.
