Heartman and sarahmarion123,
If you do a search of threads here on allnurses.com you will find a lovely indepth thread on PDA's: preferred PDAs, and some of our favorite software. I personally have a Dell Axim, they gave me a nice deal (I was a previous customer as well as a small discount for being a healthcare worker). Currently, I am using ERSuite 5.0, ePocrates RxPro and Tarascon Pharmacopeia. There are many other wonderful software programs out there but at the moment, these work quite well for me. Good luck, I think you guys (and gals) will be glad that you made the investment.

PS: On the palm platform side, there are many more free programs for it than there are for the pocket pc platform.....but I like the pocket pc platform. Feels like my desk top on my home computer!
