I am a long-time Palm user, but a new Treo user. I have had one of the new Treo 755p models from Verizon for a few weeks. It has not reset on me (apparently a problem with some 700p phones). I have read a lot of bad mouthing of Palm in general and Treo's in particular. Before I keep my 755p in lieu of a Crackberry 8830 World Phone, I thought I would see if there are GTD folks with experience (good or bad) with the Verizon-branded 755p.
PDA functions are more important to me than pushed e-mail (which may actually reduce productivity). However, I now have a hybrid system where N.A.'s and Projects are paper-based (Levenger Cira Jr. notebook), so I might be able to get by with a Crackberry for contacts, calendar, and reference lists.
I'd like to stick with the Treo, as long as reliability is not a problem.
