What the hell are you talking about? Windows NT was released in 1993, back when Apple was shipping System 7 and NeXT was shipping NeXTStep 3. Mac OS 9 didn't come out until 1999.

Actually I had Mach -> NeXTSTEP -> OS X in mind... :-)

>Nope the poster was comparing Apple Developing Macs with Ms developing NT when MS started with NT Apple was on OS9 and stayed that way for years.

Nope, the poster was comparing MS from _one era_ (when they developed NT) to Apple from _another era_ (when they developed OS X).

That is, contrasting those two transitions as different ways of building something.

oh so comapring two totaly diferent era's then?

Yes, the comparison is not about some era (what each company did at the same specified time) but about the methodology (how each company handled a specific transition to a different OS).
