I just read that in the news article today medical students using PDAs for patient care. I do not if dental students use too. But I just bought sprint treo 650 phone and PDA combine. I used to carry around PDA, phone, and MP3 player and those things got were so annoying I had MP3 on one ear and phone on other ear. I gave all those to my sister and bought the treo and it works and it's so convenient!!!!!!!!!!! 😀
