Are many of you using PDAs in the field? I've searched and found some threads in the past, but nothing too recent. And, I didn't find much about specifically they are being used. I'm considering one, but have no idea where to start. I tap into Sony's PDA site and find so much info, with little guidance as to what each will do, just feature sales, free this/that, little good info. For those using PDA, what brand, model, and why? I feel I need two primary features, a good appointment mechanism, and a good jounaling mechanism. On each visit, I have recorded what work I did, how much material, elapsed time, anything that should be noted. Therefore, I need some kind of free form, unrestricted format for a couple of lines of info. What OS does your PDA have? Do you use any specialized software, unique for the functions we might need? Or is the OS of a typical PDA provide enough functionality? I've been using a three-ring notebook, which works pretty well. But, I'm always tearing pages out, and often can't find what I'm looking for. Thanks.
