Voicemail -- I had so many complaints from friends and the cab company HQ about slow responses to voicemail, I called Sprint and told them to kill voicemail altogether. You would not believe how calm life can be without 24/7 access.
Photos -- I've been leaving the camera at home for the last several months. I bought a new video camera and I commandeered the camera bag for that, and I don't want to carry the camera in the car without any protection. When I get a new bag/case for the still camera, I'll start taking photos again.
