Robert: Mark is out, so you get the honor of approving the hard-won results of
my extensive research.

LGTM

Seems like Apple are trending towards not including accelerometers?

accelerometer sensors.
Interesting.

Definitely a trend. The point of the SMS was to detect a fall to shut down a
hard drive, so most recent MacBooks that have SSDs don't have them. But that
still sucks knowing that Apple could include them. (iPhones, etc, being the main
counterexample.)

Sigh.

On the bright side, when Apple does include them nowadays, they've finally
decided on the orientation so that we don't have to special-case as much as we
used to.
