Just becasue an application is CPU intesive doesn't mean you can't benifit
from multitasking with it. That's the best part. Suppose you are generating a
huge dbMAN report (or generating a ray traced image, or anything that is going
to take a long time). Suppose that you also want to use your computer for
whatever else at the same time. So fine! You set the cpu-intesive application
to a low priority, and start doing whatever you want! You won't notice any
slowdown, because there won't be one. If the interactive task (whatever you are
doing) has the highest priority, it will get the CPU time when it needs it. The
other tasks will just run a little slower. Small price to pay to be able to do
whatever you want while some other task is grinding away.

Generating two separate ray traced images at the same time IS silly. It would
be just as fast to do them one & then the other. But it is NOT silly to let it
grind away in the background while you go about your business.

Not everybody needs to generate ray-traced images or create huge reports. But I
do downloading, word processing, disk copying, printing, and a number of other
things on a regular basis. It is very nice not to have to wait for these things
to finish. Another added benifit is the ease of installation of little public
domain utilities... anything you want, like an alarm clock, a virus checker,
etc. can be installed as easily as running it. The way Amiga multitasking
works, when these are set to low priority, they only take processor time when
it is not being used, thus they don't slow anything down. (I'm sure there are
ways to do things like this on the ST, but they probably involve patching or
other kludges to run simultaneously, and consequently slow the system down).
