I bought one a few weeks ago. I am not really knowledgable about photography, but I can tell you that this camera takes really nice pictures. It also has a lot of features, is fast, fits well in my hands, and seems to have pretty good battery life. Go to a store and play around with it. If you need a point and shoot, I think it would work well for you.
Here is a review of the camera if you want to read more about it.
I love Canon, I am more than satisfied with my A520... and Im sure that one would only be better. Canon screams quality IMO when looking for a camera, Ive seen people buy a "awesome 4mp camera" for cheap prices, then get it home and the pictures prove that the camera was manufactured with Lincoln Logs rather then having solid construction and components.
