When Microsoft co-founder and then-chief executive Bill Gates hired Ballmer from Procter & Gamble in 1980, it was to be “the business guy, whatever that meant,” Ballmer says. Since that day, his rallying cry has always been “How do you make money? How do you make money? How do you make money?”

And this, in my opinion, is why Microsoft is in trouble right now. Apple’s philosophy is “How do we make the best product?” They figure the money will come if they make great products that people want. And they’re right. Ballmer’s philosophy led them to making shitty products that people felt locked into owning. Those days are quickly coming to an end.
