I find it interesting that Apple continues to make changes like this.
On the one hand, it's good that Apple is adding functional enhancements and re-engineering poorly designed and thought-through components of Leopard.
On the other hand, Apple had two years between releases, and clearly Leopard was a more poorly designed and buggier than any release we have seen in a very long time. 10.4, 10.3, 10.2...none of them needed patches this large or some massive re-thinks like Leopard.
I just hope Apple learns from the Leopard experience. Some components were very poorly designed, and Leopard was--and still is--way too buggy. In general, Leopard has some very poor engineering.
Apple is going through some interesting changes. I hope it is learning and growing into a great company at "the next level."
Really? I've had almost no problems whatsoever with Leopard. In fact, I've found Leopard in its early stages to be Apple's most stable and bug-free release yet! With Tiger, it was until 10.4.3 that I didn't experience hard freezes and other shenanigans... I think it's been since 10.2.5 that I've had such stability.
