I predict that there will be a kickstarter for a small attachment that will provide 3+ ports. A port extender that is attached to the side.
One port is not enough when that port is used to charge the device.
You can't even use a logitech mouse unless it is bluetooth capable!
EDIT: Something like this: http://media02.hongkiat.com/zendock-cable-management/zendock... just smaller and with two ports.
