yeah all megapixel is is the size of the picture. Most people never do over 8 1/2 x 11, if thats your case then a 3 mp camera would be fine. You want optical zoom too, that way you can zoon in before the picture is takein. With Digital zoom you zoom in after the picture is taken, which makes the picture loose resolution. I work at office max. Most people get a 3mp camera with 3x optical,3-5x digital zoom. If you spend 250+ you can usally get one that does movie clips.
