AirPlay - The Best Thing Steve Didn’t Talk About in the Keynote
So you heard about AirPlay, right? Steve kind of glazed over it a little, but here’s one of the most amazing things about it: it’s actually a rebranded and licensed AirTunes.

That’s right. You don’t have to buy multiple AirPort Express basestations to support multiple speakers anymore. Now you can choose from products by JBL, iHome, Denon and others. That means your receiver can be a selectable source in iTunes, as well as the alarm clock next to your bed.
Wow! Indeed. Thanks Jeff
