I'm most definitely _not_ Bill Gates's biggest fan, but I have to say 
that Windows NT _does_ multi-task pretty well. In fact, in a SMP 
environment, it's actually rather _more_ effective than linux, you 
can (but don't have to) force particular threads to run on a given 
processor. With luck, & provided there aren't _too_ many threads in 
the "need CPU cycles" queue, this can give you a significant 
performance boost, since the data you're working on might well be 
still available in the CPU cache, even if you've been timesliced or 
interrupted out since you fetched it - whereas pre-fetched data 
sitting in the cache of another processor is useless to you.

I _don't_ understand Win 98 multitasking. I think they got it wrong, 
Win 95 seems to me to work better. It's possible they were forced 
into "fixing" it by demands made my multimedia. The specific problem 
with Win 98 is that a thread running at higher priority is pre-empted 
by threads running at lower priority far too often - far more often 
than is needed to be able to respond to mouse clicks, etc.
