I'd say the X10 is a slightly better camera overall, low light is a bit better and I love the handling. However, the S100 is half the size, and truly pocketable. If you can deal with a slightly larger camera, I'd go for the X10. If you want the best pocketable compact on the market, go for the S100.Great timing, TCSJordan - I was just reading about this new little Canon yesterday... Still mulling it over, but I do like the size and the controls...and that nice 24mm wide angle.
Size does matter in certain situations and I'm thinking it's about the size of the GRD IV or possibly slimmer?
I'd be interested to know how you think it compares to the Fuji X10.
