Joel does a great job explaining why I’m far more excited about AirPlay than I am about AppleTV. Here are some of his imagined scenarios:
Want to show your friends your vacation photos? As long as you’re on their Wi-Fi network, you should be able to throw them up on their HDTV via Apple TV. (Or directly to the TV, once someone makes an AirPlay-licensed HDTV.)
Want to watch an episode of Mad Men you just rented again at your girlfriend’s house? Hit play on your iPhone and send it the digital photo frame that sits on her desk while you play Angry Birds.
Or maybe it’s a party, the host’s music sucks, and you want to play your own mix on their speakers. Should be easy.
