The way you use your phone tells me you only need a standard flip-phone.

I don't text/IM, but email would be good because then I don't need to be at an office -- occasionally but not much. However, I prefer a full keyboard so have stayed with a standard flip-phone from Moto and all I use it for is voice/voice mail. I hesitate to upgrade but if I do it will be to a Blackberry Curve type phone for the email commectivity while out of the office.

Not going there yet.
