PDA Question

[Prospero]

I'm looking for a way to script some equations I use for work. I'm a Respiratory Therapist and have a lot of equations that I use in the course of my work, and am looking for a way to speed things up. There not very hard, just long. I'd just assume I'd be able to do these at the bedside instead of finding some scratch paper and manualy figuring. I believe a windows ce device would be the way to go with this, but I just know nothing about them. My brother can do the scripting, I just need some recomendations about what to get. I don't need a color screen, just something with a keyboard preferably. I might be able to do this with a scientific calculator, but I would rather have the extra functionality of a pda. Thanks for any help.

What about a graphing calculator. They are very easy program and cheaper than the PDA.

I suspect I could but if I'm going to spend the money, I would rather get the extra functionality of a win ce pda. I could do more with it in the long run.
