Along the same lines as the 640K quote, I vaguely remember reading a book
that quoted Bill Gates when asked about developing any software for NeXTSTEP
(Probably porting Microsoft Office to compete against Lotus Improv and Word
Perfect) where his reply was "Develop for it? I'll piss on it!"
It's been 20 years since I saw that book and I have never been able to
confirm that was something he was quoted as saying, but it would then
explain why Microsoft entirely ignored NeXTSTEP (or they were just too busy
working on Windows and other unix ports).
