I understand that point. I need different things for different cameras. My ILC must have good accessibility to wide variety of lenses, ability to take an auxiliary flash, and an optical viewfinder, but my compact camera must only have an eyelevel viewfinder and a decent zoom range, my do everything camera must have a super optical zoom range and an eye level viewfinder, but my cell phone camera just has to have a good screen, at least some way to offer some different fields of view, produce good image quality and fit well in my pocket. And my for fun cameras can be almost anything.
But they are all cameras.
