Remember when comparing the "zoom" of various models, what many people don't realize is that they would be better served by a better WIDE angle lens. All those times you couldn't get enough landscape in the shot with your subject, etc., so don't forget to check that too!

I almost bought the Canon SD800-IS but opted for the Panasonic Lumix DMC-FX07 in the end. they both have 28mm "35mm camera equivelant" lenses, but the Lumix felt like a more solid product and it cost less. I'm sure I'd have been happy with the Canon though, if I were a "canon" person.
