FWIW, I have a 667 DVI and the battery started at 3.25-3.5 hours on a 
full charge.  It's been nearly a year, and I generally get 1.25-1.5 
hours now.  Of course, in the year, I added an Airport card (which I 
use almost exclusively for a connection), 512MB more of RAM, doubled 
the hard drive from 30GB to 60GB, and now I use a Bluetooth dongle a 
lot, so these could all contribute to the battery life.
