I would say there can be a huge psychological appeal to a certain camera. I know that I am very sensitive in regards to using certain cameras more than others. I enjoy a camera that is designed well and incorporates features (or lack of) that amount to what I believe a camera should be. I also get influenced by aesthetics...I'm not afraid to admit that. Luckily for me, I'm not buying cameras to do a job (in which I would certainly need something different than what I really want to use).
