While some people have experienced actual physical problems with 
portable batteries under OS X, for the most part the decrease in 
battery life is due to two things: OS X has a Virtual Memory scheme 
that increases hard disc activity (you can offset this by installing as 
much RAM as possible), and at present it lacks the power management 
features kept battery life long under OS 9. (That may change in a 
future version.)

So what you're seeing is probably par for the course.
