Media and MacBook updates in spotlight at Macworld

Apple's senior vice president of worldwide product marketing, Phil Schiller, took over for Steve Jobs for this year's Macworld keynote presentation Tuesday.

He unveiled updates to many Apple products, including a 17-inch MacBook Pro and DRM-free songs in iTunes.

Schiller also spent some time talking about updates to iWork, Apple's productivity suite. Those include added features in Keynote, the presentation utility (pictured above).
