This is the first feature of iOS that genuinely I wish were on Android.

Wireless mirroring of the display:

This was one of the features unveiled at WWDC and is very compelling one.

It basically throws the scene on the tablet to an external screen with AppleTV attached. I suspect that its using a DSP to compress the framebuffer and then sends the compressed stream to the AppleTV. Modern SoCs are capable of real-time video encode, especially with a stream as small as 1024x768. The speed loss would be negligible with such a setup, and make good use of a secondary core compression logic and WiFi streaming could be run in a separate thread.

This is far superior to DLNA's implementation and can be exposed as an API for more than just basic mirroring, and potentially throw to more than one display!

What's more, this can be done in reverse to produce an onLive like display for other devices in the home if inputs/outputs are a modular stream. For example, If available this would allow me the full capability of my linux server tucked away on my tablet or Eee pad transformer -- assuming of course my IA32 hardware could compress a framebuffer efficiently . Additionally, if compression is high enough, it could provide a far superior VNC like experience on the road, with minimal setup.

I hope Google is taking note of this feature. With VP8 maturing as a robust and open codec, an open protocol can be developed to do precisely this in an open and easy to implement way, and would be a boon to the platform.

I would love to see this feature on Android, Linux, GoogleTV and a host of other devices.
