I have a Canon Powershot G1 and absolutely love it. I take stills and movies with it. Canon's cameras also have the longest battery life of any digital camera on the market. If you're taking your camera on trips, this is a huge issue.

The only downside to the G1 and G2 is size. I carry mine with me in the back of my fishing vest and after standing on a river for hours, my back does start to get tired. For that reason, if you plan on carrying it with you a lot, I would recommend either the S30 or S40. Both have absolutely great quality and they are both very light and very durable.
