Better yet...
Give it a charger/stand, make it touch screen (I assume it will be already) and when not doing Skype it can be a clock / family calendar device, photo album etc. Want to make a call? Just pick it up and it will automatically pop up a menu of actions (when it is removed from the charger) including an option to voice or video call. Incoming call? Just pick it up to answer, or press the on-screen button to answer with it still in the charger.
