I have an older S300 and we love it. Is is only 2.5 pixel but still takes great on the fly pics. I would say more often then not we are shooting it rather then our D-90. I'm envious.
Very sweet Pasquale, the Canon Elph series is truly fabulous. I've got a 3.2 megapixel model that I've shot a magazine cover with ... it will be perfect for the trip.
