[MACEP] Palm: Compare battery life

[booooo]

I'm looking at getting a Palm to use for multiple purposes including:  
supervision tools, assessment, FUN (surfing, email, maybe a little  
music?, etc), Fish Tycoon!!, and of course the basics...  calendar,  
word, etc. I do understand that the more "who-ha-s" I'm using the  
lower the battery life and every day will be a little different.

I'm considering the LifeDrive and the TX.  Both are wifi, both have  
the same screen, one is bigger in both size and storage...

** Does anyone have experience with the battery life of each/either  
device in daily use?

Thanks so much!
