I agree, with one exception. When most developers think of true multi-tasking (or perhaps I should say true multi-programming) I suspect that the notion of seperate and protected addresss spaces is included. i.e. the INability of a user program to bring down the system is centeral. While USERS will never know the difference (unless they use buggy programs), developers will, and the happier develoeprs are the more user programs there will be, and the more sw available the more users there will be. So the degree with which a small number of users (develoeprs) like the multiprogramming model does have an effect on the bottom line, even though 99.99..% of users don't care. And (to lie and add another exception) users don't care how multiprogramming works but they do care that when they run some buggy programs that once in a while their system crashes rather then just that one program. This is also a bottom line, via marketing, issue since having a program crash instead of the entire system, clearly points the finger at just that one program rather than casting doubt on the entire system. (though having a program bring down your Mac is likely a very rare event, for the general user). apple!jrg John R.
