the page title is "Clambook iPhone and Android Laptop Dock". The whole page makes it seem very android-specific though, and i have a hard time understanding how anything like this would be even possible on iOS.
Well, as of now, you can actually do connect your phone to the apple tv[1]. And you can connect a BT Keyboard as well. And I think I've also seen games utilizing the second screen for a different purpose then simply for mirroring.
