The Best All Around Digital Camera

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.

The smaller sized camera designs is very portable, but usually affect ease of use and image quality in a negative way. The fringe is a camera, the smaller the controls are, which makes them harder to use. Shop "buttons and wheels are often used for multiple functions that can increase user confusion.

The best camera is SONY cyber shot and the latest of SAMSUNG with two displays where we can take pictures for ourselves.

I accept it's not absolutely in their best interests to animate consumers to alone own one absolute camera, if they can advertise them several.
