Thanks everyone for the great comments!
Simon: I'd be very interested in your evil chargers. You can contact me at kens@arcfn.com
Jerome: typically the phone contains a chip that handles the charging. According to Chipworks' teardown, the iPad uses a Qualcomm PM8028 power management chip, which handles battery management charging, voltage regulation, and other power functions. So don't worry - they're not just feeding the 5 volts from USB into the batteries!
Anonymous: I wouldn't count on the fusible resistor in the charger handling a lightning strike, since the spike could be faster than the fuse can blow. I'd recommend a power strip with a surge protector.
