Does anyone have any information on the expected battery life of the 1.25 15" vs. the 1.33 17"?
The 17 has a larger screen + higher clockspeed, but a 58wh battery vs. a 46wh battery.

Is the difference much? I've read a few reports about 2 - 2.5 hours on the 15", which seems a little light. I'd prefer to get at least 3 hours of airport based use out of the laptop at a go.

I would like to see a breakdown of real-world battery life (not specs) on rev.a 12 and 17 PBs, TiBooks and AL 12, 15, 17 PBs. Anyone have any info like that?

I am especially curious to see the rev.a AL17 vs. the AL15.

I'm slowly testing my Powerbook here at work for battery times. So far, I have 1 hour 15 minutes at full screen brightness, full CPU usage including fans on, and bluetooth active. Going to do a test tomorrow with letting it just sit to see how long it lasts. Then lastly, one with DVD playback.

Panther gives my new 17" over an hour more battery life than Jag, the Mac also runs almost 15 degrees C cooler.
