Any camera with a video display is going to EAT batteries. Its lots faster than the serial cable that's provide with the camera. SmartCards are also available in 16 and 32 Megs which can holds double or 4X times that many pictures, all in the same format. Once you shoot pictures, you can dump them to your hard drive and clear the SmartCard after each photo session. The D320 fell out of my purse Sunday and the case cracked - the battery holder wouldn't stay closed.
