I am generally one of those who is in a rush to see his his photos. I didn't like to week or turn around time for E6 4x5 or the week for mailorder 120 processing so I bought a Jobo. Now I can have my slides in about an hour.
Since this is APUG maybe I shouldn't admit this, but I do own a digital camera or two, but not because of the speed. They are great for some things. My little Sony has an underwater housing that makes it fun to capture video and images at the beach. It also takes up alot less space than my camcorder and compact 35mm camera. It also makes a great 5x7 snapshot. This is important if I just want to enjoy the day, and maybe take a shot or two to remember the place. Cell phone cameras will serve this purpose nicely when the resolution and memory increase.
