Well- from running PT LE with an mbox and a 002 for the last 2 years, I can say that my Powerbook G4 doesn't crash regularly at all. While your experience, bdemenil, goes counter to that it doesn't mean that OSX is any less stable than the *hype* would have it be.
What it means is that the engineer you saw doesn't know how to configure and maintain his system. That will wreck ANY computer regardless of OS.
Good OS is resistant to bad programs? Perhaps. Pro Tools isn't a bad program provided you run it within the specs laid out by digidesign. I ran it on a PC laptop for about a year and it was less stable than the Mac, BUT the laptop wasn't within Digi's specs. It worked, I just had to shut it down every day. And no OS or program is resistant to an ill-maintained computer, espeically for high end media apps!
In short, it looks silly holding out one example of what is obviously a computer with issues as proof that Macs can crash. To me your story speaks more to the fact that anyone can have a studio, but not everyone knows how to run one. There is a reason they were called recording ENGINEERS.
Dude. People using OSX daws have all kinds of problems. And they even talk about it. Check out the Mac forums over at the Digidesign User Conference if you have any doubt of this. Mac users don't just sit around and congratulate themselves all day about the flawless systems they own. But, being only about 3% of the computer using population, we collectively don't gripe nearly as loud as the windows users. Instead of griping about stability we gripe about price- go figure.
My experience is that mac systems tend to work better out of the box than windows systems. With proper care from that point on, they work about the same. Without proper care from that point on, they also work about the same. Mac users, per capita, tend to know how to keep their systems running better than PC users.
Take care,
Chris
