Don't forget about pixel quality (it's understandable because the industry has been encouraging it for years).
A 6MP sensor would produce a fantastic 10"-diagonal print if its pixels weren't affected by noise and it was combined with a high quality lens. Unfortunately sensors of that resolution are typically small (=noisy pixels) and placed in point-and-shoot cameras (=cramped, low-quality optics).
Or you could buy a top of the range pro DSLR from 5years ago with this resolution, with fantastic lenses and bullet proof build for the price of a modern entry level camera
