LOL - I just switched back to a paper planner for scheduling my patients. It's just so much easier to flip through everything on paper to schedule appointments, especially when I'm weeks out or need to jot something down quickly. I have a tiny cell phone that I can wear clipped to my scrub pants without it tugging them down. I do still keep my PDA with me when I'm in the emergency (toothache) clinic to reference odd drugs on a new med history. I can see where the cell phone/PDA or iPhone combos would be useful, but for me, the real datebook just works better for our clinics. The PDA was handy during the D1 and D2 years, but now that my schedule is simplified, sort of, I like the paper planner better.
Just my $0.02
