Just out of curiousity -- why?

I have a 8300 (Blackberry Curve). It rides on my hip. It works perfectly with the car.

Is the issue charging? I charge at night.

If I really needed to charge, while not pretty, I could plug it in inside the console and it would still work. I think I would only do that if talking for hours and hours on a long trip.

I think I would find it a pain to routinely have to snap it into some carrier.

Am I missing something? Is it perhaps people in poor coverage areas need this for the external anternna?

Otherwise, I think the blue tooth integration is just about perfect, I never think about it. Just make calls, receive calls... never touch the phone (never forget and leave it in the car!)
