Buying a new camera

I have an HP Photosmart (can't remember the model number) with 1MP, 2x of optical zoom, and a stupid interface which does not work as USB storage, which means I can't use it directly from MacOS X.

But this is not the reason I want a new camera. Basically. I want some more resolution and specially, a lot more zoom. Don't ask. I just love to be able to zoom.

Asking a friend, he told me that Canon PowerShot S2 IS was a good choice.
