Nope. MacOS prior to OS X was a co-operative multitasking system, just like
Win3.1. OS X is fully pre-emptive, but if you run OS 9 apps, those will be
co-operatively multitasked amongst themselves, and the OS 9 environment will
be one app running pre-emptive under OS X, just like iPhoto. Win9x/ME was a
hybrid pre-emptive and co-operative multitasking environment, WinNT/2000 is
fully pre-emptive.

Yes and no. Win9x/ME ran right on top of DOS and were still reliant upon a
lot of 16-bit DOS-like code. There is NO DOS in WinNT/2000.
