回复：You can do a comparison on Cannon website of the 2

Thank you very much! What you said is exactly what i am
thinking about! I like the zoom and lcd of Canon S3,
also like the size and weight of Canon A710, Just can
not decide which one to buy. I have a smaller one for
some years, it's always in my pocket when I went out.
You are right, nothing is perfect, but I am still expecting something perfect, sign...
Thanks again!
