Bull. They said the same thing about 7.1 and 7.2. And they'll say it again about 8.1. And 9.0. If it had none of the old Emagic code, why are many of the bugs in 7.x still there?
Every release has more new code and less old emagic code - is there any evidence that any given release is Totally Rewritten?
OS bugs, what makes you think that? And using PTHD as an example, if the bugs are the OS's fault, why does PTHD have far fewer bugs? And it runs way better on 10.5 even though digi isn't officially supporting it yet.
I'd love for both of those to be true, but what reason do you have to believe that? Or is that just wishful thinking on your part? I heard that someone asked an apple/logic rep about 8.0.2 at the recent NAMM show and their response was surprise...they thought 8.0.1 was just fine and had no idea why they'd need to update it.
I don't know which app you're using, but Logic 8 wastes a HUGE amount of screen real estate. It got better in 8.0.1 but there's still a long way to go.
He's not the only one, look at the apple user board for Logic...many many people with problems. There are plenty of problems that are 100% repeatable, I guess you just haven't needed the features that are broken. Consider yourself lucky.
