One of the high profile announcements by Google in 2012 was the adoption of the wifi standard for screen sharing and remote display called Miracast. This standard equates to a virtual HDMI cable that allows you to stream screen images or content from your phone or tablet to your TV, and vice versa. Google claimed that this innovation is a part of Android 4.2.
To date, Google has failed to make any meaningful use of Miracast across the Android ecosystem. As of December 2012, only the Nexus 4 has Miracast working, and even devices such as the Nexus 7 or 10 running the latest version of Android 4.2 have no Miracast support.
What is the purpose of a standard if there is only a single device on the market that supports it? What's the point of claiming Miracast as a platform feature when 2/3rds of your own product lineup don't support it, and none of the manufacturers in the ecosystem do?
