Apple recently posted a PowerBook technical overview PDF:
http://www.apple.com/powerbook/pdf/PowerBookG4_TechOverview_04292004.pdf
There's some interesting stuff in there, including a description of how the backlit keyboard works. The most interesting thing though is this chart about battery life:
Strange that the 15" says 3 hours for Wireless networking, while the 17" gets 3 hours 45 minutes? Yet the other times are the same between the two.
