While there is an Apple-designed Smart Cover available for the iPad and smaller iPad mini counterpart, the Cupertino-based corporation has yet to release a smaller version for the iPhone or iPod touch.
A small downside to a Smart Cover for iPhone or iPod touch could be increased friction when sliding the device in and out of your pocket, but that isn’t a problem to be overly concerned about.
Otherwise, based on the concept design above, a miniature Smart Cover could actually look quite nice. In fact, as a fan of ultra-thin accessories, I would probably want one for my iPhone or iPod touch. What about you?
