Canon Digital Pocket Cameras

I've been thinking of getting a camera, but I can't really decide. My dad's the one buying it, so he already chose his(we've been trying to pick one for a few weeks now) and it's a canon. the model number is A710, and from what I saw in-store, it's really good. I like the quality of the picture, but it's a little too bulky for me. I'm only 14, so I don't want to be carrying something that big in my pocket, just because it'd be inconvenient. Some cameras I like are the Sony model DSC-W55 and the canon model sd600.

Are there any around the size and shape of those two that have around the same quality as the A710 model? I'd like to keep the price at around $200, so I don't really want anything over-the-top. Just one that's good for zooming in(that's the main thing my dad's looking for, really) with a high megapixel count that's relatively small and not oddly-shaped. Thanks in advance for the help, since I'll probably be using the camera for the next few years.

The best camera for under $200 is the Canon A550
