Usually when Apple locks something out, it seems to mean that they've found a reliability issue and can't trust it to work. That goes back to the Apple ///s (3s) that had a clock chip that wasn't supported because it only worked on some of them.

That may be, and had they started the locking out of OS9 on G5 machines I'd agree with you.

But not on G4 machines.
