I've had a Tungsten E since about this time last year. I did get an expansion card and have most of my programs on it. Best thing I ever did. Got the hard case - I admit I can be a klutz. I now have my schedule, address book, someplace to take notes, something that can help me answer all those odd patient questions when I'm in the room (instead of having to run out and go through all the med carts to find a drug guide or calculator). No more little scraps of paper for me to lose or paper calenders to get shredded/spilled on halfway through the year.
I regularly use a program called Pepid - go to Pepid.com It is a collection of reference tools, has a drug guide, all kinds of calculators like temp conversions to equianalgesic dosing, lots of info on dx, procedures, even includes ACLS. You can even buy a Tungsten E through them already loaded with the program.
I also bought several program from skyscape: Davis' Drug Guide, RN Diseases, Taber's dictionary, and RN labs.
There is a adobe PDF for palm, which is a great help along with the Dataviz program that has a palm version of Word, and Excel. I'm going to University of Phoenix and often carry my text chapters on my palm.
The palm comes with a notes/memo program, prioritized tasklist, address book, regular calculator, photos, a clock (with an alarm), and a few other odds and ends. I keep a few photos of my niece, and vacation on it for stress relief.
There's a program called palmreader that you can buy/download and then read books off of your pda. Any type of book you like, fact/fiction/history/bestseller/romance/religion.
Check out the aacc.org website, as well as skyscape.com, pdacortex.com, and palmsource.com or palm.com you'll find lots of info about pda's, programs available, bundled offers, freeware, etc.
This is a very easy gadget to use, once you start playing with one, you'll have a blast. And yes there are even games for those times when you're waiting in line or actually have a few minutes for a nice relaxed lunch break.
