The build quality of the OG Dinc is outstanding. I've had one since the day it was released in Apr 2010 and it is still my daily driver. I've never had any problems with it, period. My only experience with the new Dinc 4G is about 30 mins in-store but I can say that it too felt solid. It has a nice heft, good feel and the fit and finish are top notch. I can only expect that it will last equally well.
