for me, like many have mentioned, it's the finer features of a PND that make it what it is. If i want to get around, it could be as simple as the old dotted line on a blank screen gps. then there are the phone apps which are okay but still lacking features, next would be the car systems which are lacking in many features and also have very short battery life like phones. The handhelds are still the most feature rich devices, i feel crippled when i'm playing with a gps in a car, both OEM built in or aftermarket. Until they fill this gap, which i doubt they will, there will be a market for standalone, handheld PND's.
