Video and Music experience should be about two things: blissful laziness coupled with minimal and seamless interaction with the outside world. With couch potato, you can sit back on your couch watching TV, wave your palm to control volume and the channel. But then imagine this! When your friend interrupts you with an instant message, all you need to do is lift a finger to trigger a smart speech-to-text reply mechanism to answer back, or message other friends, without missing a second of your favorite content!
Don't flip through tabs, don't pull out your phone, just sit back and relax!
