This week, we kick off our conversation with a discussion of the very rapid turnaround that happened this past weekend when Apple reversed its stance on paying royalties to artists and labels in the face of a blog post from Taylor Swift. Our question of the week tackles the three different flavors of Apple's operating systems – developer previews, public betas, and final releases – and what you should know about them. And at the end we have a brief discussion about Apple's ongoing licensing of the Liquidmetal alloys and what it might do with them.
