i'm sure i will buy a "prosumer" model next year, for exactly the reasons you mention. in the meantime, i can still use my SLR for those situations and be quite happy.

despite the nearly identical features and stats between the A20 and the ELPH/IXUS 300, i went with the more expensive 300 because it is just enough smaller to easily fit in a pocket, which makes it more likely that i'll carry it around and use it. you can't capture that "perfect shot" if you decided not to bring the camera with because it was too much of a bother.
