I "upgraded" to a new digital camera a couple years ago, but I've found I just don't like it as much as my old one. I prefer candid shots, so I like a camera that takes the pictures instantaneously. My current camera has about a 2-3 second delay, which doesn't sound like much, but it completely ruins candids. I like being able to whip out my camera, take the picture, and put my camera away with people going, "Where the hell did that flash come from?"
Honestly, I'm considering going back to disposable cameras. They did this best.
