"The phone space is one where we have been focusing. It’s one of those
places where we think software will be the critical element. That’s
just more and more true. Why do people like Xbox 360? Software. Why do
they like iPod? Software. If there’s anything good about the iPhone,
it’s software. How many companies in the world can do really great
software? We do it with an incredible research group, the willingness
to take on the toughest software problems, and just stick at them, and
to have a variety of hardware partners, and the biggest application
software base."

Bill Gates, Chairman of Microsoft as quoted on BusinessWeek.com (January 30, 2007)
