"The products we make combined with the apps that you create, can fundamentally change the world," said Cook near the end of the keynote. "Really, I can't think of a better reason to get up in the morning."

As expected, Monday's Worldwide Developers Conference (WWDC) keynote focused on software -- the venue, after all, was for developers who build apps and applications for the iOS mobile operating system and OS X on the desktop -- but it also included a large dose of hardware.

Apple refreshed its notebooks today, revamping both its existing MacBook Air and MacBook Pro lines but more importantly, introducing a new model in the latter, which the company's head of marketing, Philip Schiller, dubbed "next generation MacBook Pro."

"The next generation MacBook Pro is the most beautiful computer we've ever made," said Schiller, who walked attendees through the hardware refresh part of the keynote. "It's dominated by an amazing, magnificent new display."

As many pundits had expected, the new MacBook Pro features a higher resolution screen than its predecessors. Schiller called it a "Retina" display, the term Apple uses to describe the pixel-dense screens on its iPhone and iPad.
