Even that would involve filling the hull up to the lower deck with electrolyte and, to balance the pressure, probably flooding the bottom part of the dry dock with Thames water.
Perhaps the most intriguing bit is at the bottom, where rumors of a much smaller dock connector may have been validated along with a shift of place for the headphone jack.
The bottom edge -- the one that connects to the optional keyboard dock -- is home to three connectors, including the 40-pin charging slot that works with the included AC adapter.
