The overall reliability of the camera is good but not perfect. During lots of rapid shooting over the course of the initial 500+ images I experienced one corrupted image and one error 02 ("CF error, recoverable", basically a file system problem on the card). In the next thousand or so photographs I didn't experience a single error, so I have to attribute those two errors to the intentional abuse. My suggestion for now is to avoid over-running the camera's nine-shot buffer.
