50g

Hi all,

I'm a biologist who works in some remote locations, and I'm interested
in a calculator that can double as a data entry device. I know the 50g
has an internal clock -- does anyone know if it's possible to write a
program that would allow data entry with a timestamp attached to each
data point? This would be really handy for my work. If I could make
use of the internal clock in this way, that would definitely tip the
balance toward this calculator over the TI-89.

How do you find the battery life on the 50g? How many hours of
operation might I get from a fresh set of AAAs?

Thanks in advance for your help! And please forgive the naivete of a
newbie :)
