Well, the camera went back today. I thank everyone for their feedback. After further thought, the problem with the RX100 - for me - isn't that I don't think it's a good camera. I'm sure it puts out great results for its size - in fact, I know it. And I'm sure I can adapt to the camera's user interface well enough.
No, for me, it's that the total bill came to nearly $700 with refurbished camera, two-year warranty, small belt-mount case and the external charger with extra battery (both of which I feel are necessary). If I went with the brand-new RX100, the price would have been more than $800. In either case, that's more than I am willing to spend on this class of camera at this time. That's based on how much I'll likely use the RX100 versus the rest of my gear.
What's more, I could put that $700 toward a Fuji X100s or buy a Fuji X20 outright and have money left over. Perhaps when the price of the RX100 finally comes down late in its run. I could see paying $500 for the camera and charger - but that's just me. I am in no way questioning RX100 owners on their purchases. I might eventually have one as well.
