However, Bill Gates is the most important man in computing/internet history though.
Without him, not only would apple not exist (he helped apple by giving it 150 million in exchange for quicktime on the PC), the personal computer revolution would not begin and the inernet revolution would not begin, hell the digital age would not begin I could go on and on... but I think you get the idea.
Just like Apple existed when Microsoft only made Office? The personal computing revolution CAME with the Apple II. The internet Revolution CAME with NeXT and world wide web. The Digital Revolution CAME with the first calculator.
There have been far better systems all the way along Microsoft's development. Atari, Macintosh... If Microsoft didn't absolutely crush IBM Microsoft wouldn't even be a OS developer. It's indirectly Microsoft's fault we still use the incredibly outdated BIOS. IE isnt standard compliant. I can go on...
