I learned that you can disable the Sudden Motion Sensor on MacBooks by following the simple steps on this Apple Knowledge Base article: Apple Portables: Advanced tips for Sudden Motion Sensor. Why would you want to do this? In theory, disabling this sensor when you have an SSD (solid state drive) may shave a tiny smidgen of power use from your laptop, because it will reduce process poling for that sensor. If you have a HDD (hard disk drive), you probably do not want to disable this sensor.
