Once the Station is open further disassembly is pretty much self explaining. Some parts are mounted with screws, some are glued. For all screws of the station you can use a small Philips screw driver (good luck this device is not designed by the fruit company)

Now you can easily replace the battery, speakers, connectors, microphone, camera, switches, antennas, the touch screen unit and other parts.

The mechanical design appears robust. I could not really find weak parts that could limit the lifetime by design. As long it is possible to find sources for parts it is easy to repair. The only critical part is the display. The display can be easily removed but it is difficult to separate into pieces (i.e. to remove the glass on top only).
