On my more modern cameras, I tend to shoot aperture priority because depth of field is more important for most of my photographs than shutter speed. Also, on some of the later SLR's, manual focus and manual aperture control can be awkward to use at times. I avoid "auto" mode because I want more control over my photographs, but sometimes it is the right tool for the job. I don't use flash much, but when I do, I usually use "auto" mode.
I enjoy using my older all manual cameras, but I acknowledge that there is a reason camera manufacturers developed new features and functionality.
As long as "auto" mode is used as a tool and not a crutch, it is not "cheating".
