Nope, missing the concept here... essentially it would be the OPPOSITE of a docking station. No keyboard, no mouse, no built in display (just a VGA out port). Think of it as more of a networked extension/companion to the tablet. Kind of like a network media renderer/player, wireless access point, and networked storage device all rolled into one very small "transportable" piece of hardware. The relationship between the tablet and this device would be: tablet controls it, tells it what to do, etc (i.e. acts as a remote display, controller), but the device itself does the grunt work of actually playing media files, running presentation software, etc.

Does that explain the concept a bit more clearly?
