"OS2 was fine. I used the latest, Warp 4, just a coupole of years ago. But as you indicate, it suffers from 2 faults. Poor support and no applications."
Indeed.
"Porting OSX to the Wintel platform would entail bringing all the applications that currently run on it."
Saying that the applications can be ported is easy. Getting companies to port them to a platform that has no guaranteed users is different. If a company has to choose between porting its Macintosh program to Mac OS x86 or simply marketing their Windows version to Mac OS x86 users (who can also run Windows), the company will do the latter. There is no incentive for companies to port to an untested platform and there is no incentive for users to buy a platform that doesn't have the application support of the next best platform.
And that assumes that all Mac applications are portable to x86, which very few of them are. 68k and all Classic applications, Carbon applications, Mach-O applications are not easily portable. And they make up the vast majority of Mac applications. Just to get this in perspective: Microsoft Office, Apple Works, iTunes, Mozilla are Carbon applications, OmniWeb (a Web browser) is a Cocoa application. OmniWeb is portable and did run on x86 before.
"Microsoft wins due to lies and great marketing."
No, they win because people buy their products and won't switch. No lie stops people from buying Macs, no great marketing on Microsoft's side made IBM equip OS/2 with a horrible installation problem and a flaky unstable GUI.
