I personally disagree about Netscape 4 versus IE 5, and I can remember both.
You assertion about XP being better than Mac OS X, however, is hilarious. If that's true, why did XP die, and why was Mac OS X so radically more secure than Windows for the last 15 years running? Why was it more stable? Why did it work better? Why did it have a shockingly better UI?
XP was crap and we should all be glad it's dead.
Never heard about the Windows NT operating system series?
WinNT series:
WinNT 3.5 (1988-1994, based on VMS a bit on OS/2 designs) -> WinNT 4 -> Win2000 -> WinXP (August 24th 2001) -> WinVista -> Win7 -> Win8x -> Win10 (2015) [exluding all service packs]
MacOS X:
NeXTSTEP (1987-1989, based on Unix) -> OPENSTEP -> Rhapsody (1997) -> Mac OS X Server 1.0 -> Mac OS X Public Beta -> Mac OS X 10.0 (March 24th 2001, this is the first MacOS X you know) -> 10.1 -> 10.2 -> 10.3 -> 10.4 -> 10.5 -> 10.6 -> 10.7 -> 10.8 -> 10.9 -> 10.10 -> 10.11 (= El Capitan, 2015)
OS X was a worse platform because it didn't support much software - games in particular. XP was extremely solid, coming after ME in the consumer space (I had switched to W2K after 98, I took until SP2 before I switched).
So no, I don't agree with you. Even today, I think Windows is a better gaming platform and Linux a much better dev platform - OS X is insufficiently similar to Linux to work well when Linux is used in production.
