I just got a Canon S10 (2.1 megapixels) that supports 3 different image sizes (1600x1200, 1280x1024, 800x600). It's big brother, the Canon S20, has 3.3.MP and a top image size of 2048x1536. From what I've read, that kind of CCD resolution (the 3.3) is mostly just useful if you want to make 8x10" or larger prints.
