Why is so difficult for camera companies to come up with one good all around digital camera that's perfect for all occasions? I suppose it's not really in their best interests to encourage consumers to only own one perfect camera, when they can sell them several. If I were more of a conspiracy theory advocate, I'd suggest they do it on purpose. But, I'm not, and I do believe there are other factors at work here. With all that being said, it doesn't mean we can at least try to find the most likely candidate for best all around digital camera.
The three most distinguishable features or dividing factors when it comes to digital cameras are size, ease of use, and image quality. To lesser and greater degrees, these traits seem to be mutually exclusive when it comes to camera design and build.
Smaller sized camera designs are very portable, but usually affect ease of use and image quality in negative ways. The smaller a camera is, the smaller the controls are, which makes them harder to use. Single control buttons and wheels are often used for multiple functions which can increase user confusion. Smaller cameras often mean, that features like viewfinders get left off in the effort to add bigger LCD screens. Smaller often means zoom lenses are less powerful, and overall lens quality suffers. The most successful small sized cameras I like are the Canon SD1000 Digital Elph, and the Olympus Stylus 790SW.
Ease of use usually means lots of auto settings, which is great for newbie photographers, as little skill is required to snap a picture. But, it also means camera designers are forced to compromise on default settings that are OK for most pictures, but not great for all pictures. Factory set defaults will have to do until cameras become smart enough to detect all the nuances of a particular shot regarding lighting, color, and artistic intention. The Canon Powershot A570IS is one of the better cameras in terms of simplifying things at a reasonable price.
