PDA software

I am currently working in Canada and use my PDA at work all the time. I use epocrates as a drug book. You can get a free one from epocrates.com and I find it very useful. Sometimes the drugs are listed under different names but usually if you look for the generic name you can find it. Occasionally I find drugs that are not on my palm, but then anywhere I have worked there has been a current CPS handy or a smaller drug book, so it has never been much of an issue.

As far as other software is concerned, do a search for PDA software online, it really depends where you will be working as to what you might need, I have a med calcualtor etc, but really don't use them.
