In my opinion, which is not the gospel by any means when it comes to digital cameras. You need to decide how big of photos you want to get out of the camera. If it’s strictly for emailing pics and posting to a web page for fun, a 1.3 megapixel camera will be just fine. If you think you’ll want to get these pics actually developed, then you should go with a 2.1 megapixel, minimum. I see they have 5.24 megapixel cameras out now, but I really don’t see the need for such high resolution. Another feature that is important is the optical vs. digital zoom feature. The higher the optical zoom, the better. I’ve got the Kodak DC215, a low end digital, that takes good enough pics for the boat and to send via email.
Good luck with your choice!!
