Actual Ti800 Battery Life?

2-3 hours sound about right. I can get just over 3 hours of general usage (web surfing, emailing, etc.) while sitting in my sofa connected via AirPort. So I presume I will get a tiny bit more battery time if I connect via ethernet.
Once I got over 4 hours of battery time when I use my Ti800 as a MP3 player only on the plane. I turned the screen brightness all the way down to black and just run iTunes. Pretty impressive considering the amount CPU iTunes uses.

Battery life will also be affected if you have the hard drive set to spin down or not. I never let mine spin down, nor do I dim the screen. I still get close to 3 hours of battery time out of it. If I was to let it dim and spin down, I could get even more time out of it.
The airport card doesn't draw a hell of a lot of power, so I don't see it extending, or cutting down, the battery time.
When you charged the battery, did you follow the directions in the book??? I seem to remember it saying to allow it to charge for several hours before discharging it. Like over night (~8 hours). You really don't need to discharge and charge the battery more then once every month or three. The new batteries are nothing like the old ones, which needed to be fully discharged or they would be paper weights.

If I downclock to 667 and turn screen brightness all the way down, I can get about 4.5 hours of typing work out of mine.
I like the screen nice and bright and the processor fast...
The ONLY time I could see doing either downclocking or dimming the screen is if you really MUST work on it on a plane, and you didn't have either a spare battery or one of the airline adapters (for power).

Lind electronics has one that doubles in autos also (works for three different generations of PBs) - alas I have never been on a plane that had a plug-in.

you can go into system prefrences > energy saver prefrences and then the options tab, you can then choose if you want to check the box 'reduce processor performance'
i think that on the 800 it will bring it down to 667MHz. i'm not sure what it will do to the 667... and it's been there since 10.1.3, and probably before that.

Alas I only had my 800 Tibook for a few months and am now back to my trusty Lombard - no option for processor speed. Needless to say that is the least of my disappointments

L3 cache gets turned off
On both new tibooks, cb911, the L3 cache gets turned off when 'reduced processor performance' is checked. Also as you mentioned with the ti800, the processor speed is reduced to 667 mhz.
