Digital cameras are amazing products. But it won't pay to rush into a purchase unless you're a professional photographer, a real estate agent, a Web page designer or can otherwise anticipate a good return on the investment.
These are relatively expensive cameras with complex features, and their prime buying criteria, image resolution, has morphed from 1 to 5 megapixels--for now. The residual value of just about any model will be undercut by more fully featured cameras that follow at lower prices. Yes, that's true of most technologies, but this is ridiculous.
