Iphone/Itouch and epocrates will take care of just about all your needs. As a 4th semester student I waffled for a long time about what to get and finally pulled the trigger in the 3rd semester after my preceptor asked me how I kept up without one. I told her that it was all in my head and she didnt like that response so I showed up the next clinical with PDA in hand. I tried out a friends palm and found it not even close to user friendly to get set up on your computer and downloading to mini disks for updates and synching was always a hassle. Apple has a rep for being user friendly and in this case it is absolutely true. During class lectures I sit there following along with Epocrates to see if it agrees with the lectures and what key words I have to use to find the info so later on I am quick to find what I need. Good luck.
