Here’s a snippet from Steve Jobs’s iPhone announcement:
Well, today, we’re introducing three revolutionary products of this class.
The first one: is a widescreen iPod with touch controls.
The second: is a revolutionary mobile phone.
And the third is a breakthrough Internet communications device.
So, three things: a widescreen iPod with touch controls; a revolutionary mobile phone; and a breakthrough Internet communications device.
An iPod, a phone, and an Internet communicator. An iPod, a phone … Are you getting it?
If the app doesn’t contribute to one of these three things, delete it.
1. Music. This should be the extent of your entertainment.
2. Phone. This should be used to communicate with friends, family, and customers.
3. Internet communications device. This should be used to learn about your industry, the world, and to communicate with your friends, family, and customers.
