Bill missing the whole web stuff was more about their lawsuit because regulators believed that only through the browser on Windows people could access the internet. Which was a wrong prediction.
And Ballmer...Yeah. He fumbled hard with mobile. And thanks to the board stopping from buying Yahoo. Would be another AT&T merger fiasco.
With billg missing the dawn of the Internet, I didn't mean the IE integration fiasco and the resulting lawsuit - that's actually the part they got more or less right (in their own perverted 3E approach, not according to my moral compass), but too late to become dominant. They first wasted time trying to create their own MSN walled garden a la Compuserve .
To Ballmer's credit he did start Azure, although it doesn't feel it was a serious enough effort, until he was replaced. But between Vista, Windows 8, Windows Mobile, Nokia, Skype, Zune, Kin, etc etc... it's no wonder it's been called Microsoft's lost decade.
