From John Gruber @ Daring Fireball:
Microsoft looked at the PC market and asked, “How can we make the most money?” Their answer was to sell software to the business market, because that’s where the money is. Pure pragmatism: corporations are conservative, change slowly, and hold compatibility (and low prices) in high regard.
Apple looked at the PC market and asked, “How can we make something better than everything out there?” Their answer was the Macintosh. Pure idealism.
He goes on to say that Apple couldn't have had compatibility AND "insane greatness" at the same time. And it kind of goes along with the story that the Apple folks were a bunch of crazy hippies working on changing the world.
