Apple has long focused on providing the best user experiences in the world. The original Mac team labored over making the computer hide the complexity of the software underneath in order to become the "Computer for the Rest of Us." The same is true of course for the iPad, iPhone and iPods. What looks easy to use is of course very hard to create.
An interesting story today in the Wall Street Journal about how this focus on great user experiences dovetails with Apple's M&A activity. This all goes back to the desire to do one thing better than everyone else – and that starts with focus.
While Apple could improve lots of other consumer experiences it can't allow itself to be defocused or the areas where it does apply its magic may not succeed.
All entrepreneurs should take note: fix something that's broken by focusing on making whatever came before much easier. The market will follow.
