I love my 80D with 15-85 and 70-200 combo and the image quality is fantastic I'm just tired of carrying it around. Normally the best photo opportunities I have are out hiking but find myself leaving it home and taking my G15 which comes nowhere near the image quality. So with the G1X1 I'm getting a little closer at least and will be able to get some decent quality pics when I'm out hiking.
Getting a G1X3 would essentially give me similar quality to the 80D. Plus I'd have the benefit of having it with me more often and not be burdened by the weight.
I agree completely.
Here is a test shot outside the camera store... It's not quite as crisp as the original image but it gives you an idea.
