The desktop metaphor was invented because one, you were a stand-alone device, and two, you had to manage your own storage. That's a very big thing in a desktop world. And that may go away. You may not have to manage your own storage. You may not store much before too long.

For the past 33 years, I have looked in the mirror every morning and asked myself: 'If today were the last day of my life, would I want to do what I am about to do today?' And whenever the answer has been 'No' for too many days in a row, I know I need to change something.
