What machine do you have and under what conditions?
I did a test a couple of days ago with my i7 MBP 15" and got almost 5 hours before it threatened to shut down. I turned it down to 50% brightness on the LCD, wireless only, with about 4-5 programs running and used only the Intel graphics chipset. It was also running an Apple keyboard and USB mouse.
I'm ambivalent about the result because it's not much different from having a spare battery.
