Battery life on last rev powerbooks.

I'm going to get a last rev powerbook, I thought I was going for a 15" but I'm still mulling over getting a 17" if a good one becomes available. By good I mean one that has the 128mb card and 1680 x 1050 (or whatever the exact res is) and the 7200rpm BTO drive.

I may end up getting the 1440 x 960 15" last rev powerbook in the end.

I believe that the battery life was improved in these last rev powerbooks.

My question is... Comparing the 15" last rev powerbook with a 5400rpm drive with a 17" powerbook with a 7200rpm drive, is there much difference in how long the batteries last under similar usage? I suppose that the 17" display will use more power but I don't know if it has a better/bigger capacity battery or not.

Also does the 7200 BTO drives use a lot more power or negligibly more power than the 5400 drives.

The last rev Powerbook had a 1440 x 900 screen resolution for the 17" screen. The 15" was lower. The 17" also had better battery life than the 15". That's all I can answer for now. Of course if you're talking about MacBook Pros instead of Powerbooks then you're right. I'm not sure if they even offered 7200rpm as a BTO option for powerbooks.

I can assure you that the last rev 17" was 1680x1050 and the last rev 15" was 1440x960. And there was a BTO 100GB 7200rpm drive offered.

Some further research has shown me that according to specs I've found the 15" and the 17" have the same battery life.

This is somewhat puzzling to me. Does that mean that the 17" had a larger battery? If not, what is the real world battery life of the 17" compared to the 15".

Also does a faster HD have much effect.
