Wow, so yesterday I went from ATL to SNA and I saw battery times of as much as 8:42 in the battery meter at 93% power. Finally, I have a MacBook with amazing battery life! 
This was achieved using just Keynote, with BT and Wi-Fi off and brightness set at 1 segment. My guess is that with actual use, i.e. multiple apps, etc., you could get at least six hours with this great lappy.
