Paul Graham writes in Return of the Mac:

In the matter of “platforms” this tendency is even more pronounced, because novel software originates with great hackers, and they tend to write it first for whatever computer they personally use. And software sells hardware. Many if not most of the initial sales of the Apple II came from people who bought one to run VisiCalc. And why did Bricklin and Frankston write VisiCalc for the Apple II? Because they personally liked it. They could have chosen any machine to make into a star.

Now I don’t know if I’ll sell any Mac hardware because of my apps, but maybe I’ll entice a few people to move to Tiger.

What I do know is that I love my Mac and I love writing software. So the two go hand in hand, like chocolate and peanut butter.
