I decided to go with Canon and the S90 over the Panasonic because of the 28-105 zoom range which for me is more useful than the 24-60mm of Panasonic. Panasonic also has a long history of over aggresive use of noise reduction. Finally, the lens ring system seems to be a dramatic step in faster and easier use of the camera. I am not sure if Panasonic uses their little paddle control but when I tried it I could never get use to it. I hate it even more than Canon's revolving ring of the 4 way button control.
