I would like to use this definition: "In a true multitasking system, tasks can run independently. They can also communicate with and interrupt each other." -- Caia Grisar, MIT Information Services. I do not understand how a system can be non-preemptive multitasking. Also, this may be just a slip of the tongue (finger?) on your part, but NeWS, SunView, and X are all _windowing_systems_. For example, it makes no sense to discuss the "multitasking" of X because X is merely a set of programs that interface to mouse, keyboard, and screen. Multitasking has to be implemented in the operating system, in this case Unix. This is partly why I feel MultiFinder is not multitasking; it was not written as part of the OS, it was added later. > It (MultiFinder) presents a single, easily >learned, consistent interface across all applications.

Multitasking is about _multiple_tasks_, not user interfaces. > A comparison of simplicity between multitasking and MultiFinder >is relatively useless because multitasking is an operating system concept >featured within MultiFinder. Surely you're not saying multitasking is a subset of MultiFinder? Please explain. If you really are saying that MultiFinder "is fully and completely multitasking" you're on pretty shaky ground. Multitasking systems preempt. Multitasking systems run tasks independently. Multitasking systems are simpler to implement and interface with. > To compare apples with apples, let's compare >windowing systems. That was not the intent of my original posting. If that's what YOU want to discuss, why are you following-up? As I understand it, MultiFinder is not a windowing system. MultiFinder is an addition to the operating system. > All other things equal, which they basically are, ^^^^^^^^^^^^^^^^^^ >consistency makes the Macintosh interface and MultiFinder simpler to >learn and use than X, NeWS, or SunView.

I have my opinions and I enjoy discussing them. Your comment precludes any discussion between us; you imply my opinions have no value because I am a student. If I agreed with you you would not make the same comment. And why do you assume I have no real world experience? Have you never heard of people working for a few years before returning to college to complete their degree? Nor do I understand your comments about Unix. I never claimed Unix was the world's salvation. I never mentioned Unix at all. I acknowledge the reality of several million Mac users (my last posting). But you still have not addressed my main point: As a tool for switching between tasks, MultiFinder has absolutely no advantage over multitasking. And at least one disadvantage (which you have granted me). > > David W.
