I need to have a PDA for references during clinical hours, I am now a full time student trying to save on every dime so; anything with a recurrent monthly bill is absolutely out. I need a wi-fi PDA so I can acess epocrates, ovid, MDconsult etc... while on clinical site. Budget is very tight but will try to spend if need be. What reliable PDAs have worked for students and clinicians in this high tech world of ours. I find myself spending hours to research and can't seem to make up my mind. Any suggestions will be very much appreciated.
