Brother, what a load of crap. Don't be afraid of technology. Ok, great you got the dose memorized, so what. What are ALL the side effects of the drug and how often do they occur, what is the metabolism, half-life, mechanism, what are other uses for the drug, etc..
Of course you have to know a great deal, but first you have to learn it. I've found that the palm is a great way to look up something real quick, right after seeing a patient or talking about one. It helps you learn.
I didn't use it to track patients since I need a less structured way to track all the little details and this is often just too complicated/time consuming to do on a palm. And I use it as a reference and aid to my readings. What ever works for you is the right way no matter less open-minded individuals say.
Cheers!
