Just to get it straight: the Mac will have virtual memory in System 7. 
(Actually, you can get it now.  I'm running VM on a lowly Mac II w/PMMU right
now with the help of Virtual.  But that's not built into the OS, so that's
not really addressing the OS point above).

The Mac also has multi-tasking.  It is cooperative multitasking, not
pre-emptive.  I know which one you prefer -- and there are good reasons for
that --  but they ARE both multitasking.  If you disagree with that, please
direct followups to comp.sys.vm.here.we.go.again. 

One other thing the Mac OS doesn't have: protected memory.  That seems to me to
be more important than pre-emptive multitasking.

Of course you can always run A/UX and get all of the above goodies, even w/o
waiting for 7.0.  But of course you wouldn't, 'cause Apple is Evil and Steve is
God, right? :->
