No, I'm sure Al Gore invented EVERYTHING involving computers and the Internet; after all, he got a Nobel Prize! (or maybe it was an IgNobel prize http://en.wikipedia.org/wiki/IgNobelPrize - something like that)
History only remembers the big picture. Sure, there had been other companies fooling around with "computers". However, Apple had figured out how to best package that technology into the first PC.
If it had not been for Apple's leadership and innovation, we would not have the computers that we use today.
"The company introduced the Apple II microcomputer in March 1977. A few years later, in 1983, it introduced the Lisa, the first commercial personal computer to employ a graphical user interface (GUI), which was influenced in part by the Xerox Alto. Lisa was also the first personal computer to have the mouse."
