This worked great on my aging macbook. That's just amazing, I had no idea it came with sensors to support such functionality.

  All Apple laptops since 2006 have had a sudden motion sensor to detect when the laptop is falling and lock the hard drive platters in place to prevent damage. Apple exposes this to software basically just because they can, AFAIK. And to support cool features like this. http://en.wikipedia.org/wiki/Sudden_Motion_Sensor http://en.wikipedia.org/wiki/Sudden_Motion_Sensor

    It appears the new macbook air no longer includes the motion sensor since it was originally designed to protect the hard drive, and the new air is lacking one.
