Remote controls for watching TV are a thing of the past, even the sophisticated ones produced by Logitech.
Soon mobile phones are going to take over remotes.
See in the above's video the new Google's app for its Google TV Interface that works on Android devices. It allows users to control their program guides, access their DVRs and send content from the mobile device directly to the TV.
Notice that a growing number of viewers are using mobile phones in the living room texting and browsing the web while watching TV. So extending navigation to those devices makes sense.
