What's an antennae, "inbox", and a "call me now" message doing on an iPod Classic?
This may not even be a Classic, but a placeholder for an iPhone with a sort of physical input. The Clickwheel is too Nano-ish if I do say so myself.
It may also be to protect the details of an actual product. By showcasing your new ideas on an old product, you get to patent the ideas without giving too many hints to the competitors.
