I just bought a Canon PowerShot S400 (just as in before my trip to Alaska 2 months ago), and other than many recommendations for Canon from friends, I used
Digital Photography Review and
Epinions.
I'm very happy with the camera itself. The software on the computer could be better, but you don't *have* to use it if you have XP since it can download pictures from cameras on its own. The advantage of using their software, though, is it'll auto-rotate the pictures since the camera remembers what the orientation was when the shot was taken. This information is stored separately (the picture on the card is always in landscape) but their software will do the transformation on the downloaded pictures if you use it to download them. I've just lived with their software; it isn't horrible but as I said, it could be better.
Canon has a few different lines of cameras from the small Digital Elph (which mine is) through their SLR cameras on the high end. I've also heard good things about Olympus cameras, though I don't have any personal experience with them.
