What advantages does 'true multi-tasking' (by which I assume you mean pre-emptive multi-tasking) have over Apple's co-operative multi-tasking? Co- operative multi-tasking has significant user interface advantges over the pre-emptive kind. I for one would rather not have my application pre-empted by a background process in the middle of say a menu selection. Any one who has used TOPS while a large file transfer is in progress can attest to the fact that having the interface slow down is a real drag. (TOPS for those who may not know, is an AppleTalk fileserver system that runs in the 'background') Anyone who has used Suntools on the Sun's can attest to the horrible things that can happen when your're trying to get a menu up but the processor is too busy servicing some other process. Sure, pre-emptive multi-tasking makes it easier for the programmer who would rather not worry about whether he's in the background or whatever, but it's the user's view that matters most. That's what the Mac's all about. ____________________________________________________________________ Have a day. :^| Murat N.
