On January 5, 2000, Steve Jobs unveiled the Aqua user interface for the very first time. Stylistically, it was a bold departure from what had come before, and was no doubt created with the iMac G3 in mind.
The changes were more than skin deep, and no where was the influence of NeXT’s software more evident than the Dock, a place for users to stash documents, an easy way to launch applications, and generally anchor the user interface to the bottom or side of the screen.
