I also own my Canon PowerShot S2 IE for a couple of weeks now, and I'm very happy with the results. It has 5 megapixel and a 12x optical zoom. Several people here have that cam and you can see the results here. It's taking phantastic macros, but also landscape shots turn out much better than with my old cam.

There's also a lot of discussion about that cam in that thread.
