I love the tungsten E. It has plenty of memory and will accomodate a memory card as well - will hold plenty of nursing-related stuff as well as personal calendar, photos (although it does not take photos as does Zire 71/72) and also interfaces with Word, Excel and PowerPoint allowing for viewing/editing of documents - good for students. It retails for around $200. I think Palm has updated it but the price should be about the same.
The Palm calendar can also be set to interface with outlook on your PC so that is a nice feature as well.
As far as I am concerned it is the best all-round value and model.
There is a site called
www.pdacortex.com that has a listserv you can join - lots of very knowledgeable people - and freebie software to download.
Also if you will visit
www.freewarepalm.com they have some good things under their medical section (and a few good games too, good for waiting rooms and such).
Disadvantage of the TungstenE - its not waterproof (LOL)!!! My daughter spilled iced tea on mine and it died...now I have to wait to be able to afford a new one...I'm lost without it!!
