Apple raised the curtain on HomePod, its upcoming smart speaker, during Monday's keynote presentation at its Worldwide Developers Conference. The company also announced some desktop OS features for the iPad, and revealed its plans to become an augmented reality powerhouse. "Just like iPod reinvented music in our pockets, HomePod is going to reinvent music in our homes," Phil Schiller, Apple's senior vice president for worldwide marketing, told an enthusiastic crowd at the San Jose Convention Center in California.
