Hasn't always been the case about upgrading speed...7.1->7.5, 7.6->8.0, 8.x->9.0, and who can forget 9.x->10.0, which was also a downgrade in terms of functionality (some of which may never return, like tabbed folders...lamina said:With Apple, I've noticed some speed INCREASES when one upgrades. That's the way it should be; an upgrade is actually an upgrade in speed, as well as functionality.
However, the strides Apple has made since 10.0.x->10.4.x are amazing in terms of speed. When I first used X (10.1) it was an awful, horrible experience I wouldn't wish on anyone. Even though my hardware has been upgraded, 10.4 has also had a role in the speed increases.
