The batteries, with the 5800mAh battery belonging to the 900 and the 5200mAh battery for the 701. The batteries are also cross compatible among the two models, although there's a slight change in voltage as well.

The two adaptors. The 701's adaptor is actually bigger than the 9010s brick! Do note that although the batteries can be used on both devices, the 701's adaptor does not work on the 901; the sockets are the same, but the 900 will refuse to charge with the 701's adaptor.

As mentioned the socket and battery pins are exactly the same.

Difference in power draw due to the bigger screen on the 900.
