You do know that Jobs copied the GUI idea from Xerox?
The Mac user interface was inspired by some concepts at Xerox PARC (and Stanford and other places), but the look-and-feel of the Mac GUI was substantially different from the Alto and Star, including a lot of Apple innovations like desk ornaments.
In contrast, Microsoft shamelessly attempts to copy the look-and-feel of Apple's user interface technologies. The Windows 7 demo probably infringes on some of Apple's patents.
