First, if you get a 700, get a 700WX. The memory is double what it is on a 700W. Whether or not you can send MMS depends on your carrier (Sprint was not allowing that for a while). I have VZW and can do so. Dont know if Alltell will allow that. As far as the Treo 700WX as an all round device, I'm very happy with it. With a few tweaks and add ons, you can pretty much have one hand operation.
