why not add functiinalities to the pen - like 3,5mm ( with some memory it could be used as portable player. even with out memory it could be used over bluetooth - with cable headphones). add mic and speaker ( and it could be used as "phone" or dictaphone ). you are plugged your phone to charge but have yours pen next to you for conversations
