The second thing I learned was the height/width pixels on my wife's new point and shoot are twice what my old "good" camera has.  So while I may have 10x zoom and she only has 5x, she can take a picture a 5x zoom and crop it to what I took at 10x zoom and her pic which have the same detail as mine.

Important to remember the size of the chip that those megapixels are measured on is important. Thus a full frame 20mp captures much more detail and dynamic range than a 20mp point and shoot. Think of it like film size, the chip on a point and shoot is tiny compared to that in a DSLR.
