I have a couple of Canon digital SLR's and they are great if I'm going somewhere to take pictures. However, I'm looking for something that I can keep in my rucksack when I go to work or visit friends/family. So I am looking for a smaller compact camera that I can take with me on such occasions. It needs to have an image stabalised lens with a reasonable zoom on it, be light and also have a good "video" mode. After a lot of research, the Canon S3 IS seems to fit the bill. Has anyone used this camera? What do you think of it and does it work well with the Mac? Finally, if you didn't like it, what was wrong and did you pick something else? Thanks in Advance.
