I love all the hype around products and especially as people start to dive into them. This is when you start to hear about all the stuff that's not included in that new shiny toy.
Take the AirPlay functionality in the new Apple operating system for example. It's supposed to let you stream content from any Apple device -- iPhone, iPad, Macbook, Macbook Pro, etc. and play on any other Apple device on your Wi-Fi network via Apple TV.
So if you downloaded a movie in iTunes via your iPad, you can then stream it to your TV through Apple TV.
All this is cool, but there's one bit of functionality that AirPlay can't handle according to Daring Fireball:
Basically, you can't play video that you shot on your iPhone through Apple TV or even video you created in iMovie for the iPhone.
That's pretty weak, but I'm sure it'll be addressed in a fix at some point because what's the point of shooting video on your device and NOT being able to share it on your home network. Having to upload to YouTube each time would be a PITA.
