Have a pocket pc myself. There were times i'd have liked to have a palm OS, since my classmates were busy beaming their free programs to one another. Free programs for pocket pc are a bit harder to find. Used my PDA mostly for the calendar (keeping track of where i was supposed to be for conferences, clinic, etc) and Epocrates in 3rd yr. Now, as a 4th yr, i've also "regressed" to using my tarascon and other paperback references. I've used my PDA so little this year that my main battery ran out, and i need to totally reload everything back onto my PDA after i recharge it.
