I can see a long term goal: The smartphone as central authentication key which enables access to applications and data on host tablets, computers, terminals, which will extend funcionality (input devices, display size, physical media...) and improve networking capabilities. This is not it. It's a stupid display, with difficult physical access to the docked device, no real benefits except a minor increase in screen size with the drawback of an additional device and decreased mobility.
