At least photos on a phone are less likely to be used to torture others later - the old slides and videos could be a nightmare for friends and family. For some reason people are generally incapable of culling their collection and only showing the good slides, and most people's video skills are not that great.

I was at Port Arthur many years ago watching a couple with their video camera. The entire trip was just her videoing him standing in front of different buildings. I imaging their narration when they got home was along the lines of "this is Harold standing in front of an old house, and this is Harold in front of an old building. Was that the Model Prison Harold? I don't know, it had some sort of name. I don't know why they called it that, it doesn't look like a model. There were signs up but I didn't have time to read anything because I had to stand there with the video camera while Harold stood in front of the building". The family probably still have nightmares.
