For any situation where sockets are required there is one golden design rule. Look at the sockets. Are they ugly? Will they spoil the beautiful lines you've designed in? Will they speak the same language of design? Apart from plugging rank and nasty things in, is there any point to the sockets? Will you use the sockets in a coffee shop?
Ditch the sockets. If you want room for expansion, buy a tracksuit.
Never forget that the ideal Apple computer is powered by your adoring gaze and your friends' envy.
