Here is a typical 6.6 megapixel satellite pic I edit and print. It is 300x300 and goes to poor quality when printed at 8x10 and is unuseable at 11x17.

I like the >10 megapixel cameras that are now readily available. The better cameras are pushing 14 megapixels. Still, the lens is the most important part of a camera, pixels be damned.
