Sorry for the delay in responding. These came in while I was at Macworld Expo.

The battery on the MacBook lasts longer than the MacBook Pro for both Mac OS X and Windows. The primary reasons are that the processor is not as fast, the screen is not as big, and the MBP has its faster graphics processor turned on for these tests.

Make sense?
