Pocket Camera Suggestion

I have a 20D and G5. I'd like something that is truly a shirt pocket camera. I would prefer Canon but would consider others. Any advise?

I like my sony t10 .... it is very user friendly and has imagestablization built in.
I like the flip lens cover on the front the best. When I need to capture something real quick I just retrieve the cam and flip the cover down and its ready to go. Image quality is pretty good too im sorry I dont have something to post to show you. My choice was between three point n shoots Canon SD630, Nikon S7c , Sony DSC T10. I hated the canons menu but the picture quality was great. The nikon had some cool features like built in panaromic photo mode ... you have to go play with one to see what I mean. I just hated the buttons on the nikon they were too small. The sony was the easiest to use for me and the menu was easy to navigate.

I suggest you do what I did, I bought each one and took it home and played with each one for a day or two.

As I was considering a small P&S camera for my parents, I looked into the SD600. It's really small and very light, I think that you should check it out.
