“One of my favourite Steve Jobs stories was the time the engineers working on the iPod brought their finished prototype to him in his office. He said it was too big, they needed to make it smaller. They said it was as small as they could make it, it couldn’t be made any smaller. So he took the prototype over to his aquarium and dropped it in. The iPod sank to the bottom, and as it did, tiny little bubbles came out. ‘See those bubbles,’ he asked. ‘They’re air inside the iPod. Make it smaller.’ – Fuiru
No idea if this story’s true or not, but a great story nevertheless.
