I guess like everything else it comes down to personal preference. I still think I am leaning towards having both, but using just one at a time. For those that have been saying how unstable the Treo is, and while I can't say for everyone, I've had a BB 8703 for a couple of months now and have had more dropped calls than I ever had w/ my Treo. The Treo did freeze up twice on me, while my BB has only done it once. Maybe it is because I switch phones so often being a gadget freak
