Same old story as many other people. Trying to decide between 550 and 640.
Can any 550 users tell me, please, how well the processor runs the maps when you're driving? That's all that really matters to me - sit the phone in the holder of my car and use it as a SatNav to my appointments, take it in with me, make some calls, leave, phone back in holder and act as a SatNav back home again. I've checked the navigation specs, and I see that it should in theory run perfectly fine for the job, but just concerned about it stuttering through map directions as I'm traveling. So I was hoping to get feedback from owners who have used it for this purpose?
