Another voice in the Canon camp. I have an S400 as well and love it. I also have a big DigiSLR but I always have the 400 with me so that's what I take most unplanned shots with.

I'd look at the SD200 for an inexpensive pocket camera. The baby-brother SD110 is nice, but for a small price increase go for the 3x vs. 2x zoom lens.

I'll also add a vote for www.dpreview.com and add www.steves-digicams.com as an invaluable resource as well.
