Hi, i would love that you add something to the case so we could clips a backpack under it and that the backpack has access to the usb port and maybe some other useful connection.... that would be useful for making dock or also can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs, by only using the usb and a controller like the Arduino (see arduino.cc) and a lot of other useful project would be much more easier with this.
