Microsoft .. a bunch of lamers !!!, page 2

Beginning in 1979, started by Steve Jobs and led by Jef Raskin, the Lisa and Macintosh teams at Apple Computer (which included former members of the Xerox PARC group) continued to develop such ideas. The Macintosh, released in 1984, was the first commercially successful product to use a GUI .... A desktop metaphor was used, in which files looked like pieces of paper; directories looked like file folders .. there were a set of desk accessories like a calculator, notepad, and alarm clock that the user could place around the screen as desired; and the user could delete files and folders by dragging them to a trash can on the screen .... Drop down menus were also introduced.
There is still some controversy over the amount of influence that Xerox's PARC work, as opposed to previous academic research, had on the GUIs of Apple's Lisa and Macintosh, but it is clear that the influence was extensive, because first versions of Lisa GUIs even lacked icons. These prototype GUIs are at least mouse driven, but completely ignored the WIMP concept ... Note also that Apple was invited by PARC to view their research, and a number of PARC employees subsequently moved to Apple to work on the Lisa and Macintosh GUI. However, the Apple work extended PARC's considerably, adding manipulatable icons and a fixed menu bar and direct manipulation of objects in the file system (see Macintosh Finder) for example. The modern GUI as we know it owes as much or more to Apple as it does to PARC - it is incorrect to claim that Apple "copied" or "stole" PARC's work. A good article pointing out many of the significant improvements that Apple brought to the GUI over PARC's implementation can be read here (folklore.org)
The Macintosh's GUI has been frequently revised with time since 1984, with major updates including System 7, and underwent its largest revision with the introduction of the "Aqua" interface in 2001's Mac OS X.
