In theory, I love the idea of PDAs. I love the idea of having an up-to-date drug book that I can carry around in my pocket. In reality, I've been disappointed with my Palm and I find I don't use it very much.
I don't like having to scroll to find information about a drug. I just prefer the format of a book, where I can see the whole page at once. (My personal preference and I realize not everyone feels the same.) I've had endless problems synching the device with my computer, and compatibility problems with one program or another.
I prefer a paper and pencil calendar, and I use the calendar reminder feature on my computer to alarm for certain events. I just don't use the calendar on my palm. (Again, my own personal preference. Call me old-fashioned.)
We have Lexi-Comp on our Pyxis machines at work which I can use to look up drugs that aren't in my book.
One program I really love for the Palm is the Tabor's dictionary. But that doesn't justify the cost of the machine and the program to me. I probably won't get a new Palm when this one becomes obsolete.
