This is misleading, Jef Raskin was the father of the Macintosh, and GUI concepts predated Xerox. Apple built a new product with a different purpose from Xerox using some of these same concepts and inventing others. link
I started with an Apple ][+ in high school, couldn't afford a computer in college, but used many SE's, ci's, cx's, in the lab for classwork (BFA). Post college, at work I've used quadra 650's and all sorts of PowerMacs.
Still own a Classic II, a G4 Cube, a G5 PowerMac, a i7 iMac, and all sorts of iPods/iPads.
