I just ordered Ricoh GR. It appeared into a Finnish web store this morning and I immediately made my purchase. I am selling my Sony RX100 now.
I was not enjoying Sony enough to keep it. It is small and handy but GR is not that much bigger. And 90-95% of the shots I took with RX100 were at 28mm. I was not much zooming with it. GR has 28mm equivalent lens, so it should suit me well. So, my decision has been made. I have longer lenses (50, 80, and 200mm equivalents) for my X-Pro1, so my needs are quite well covered.
I am not sure when the delivery of my GR will be but the first estimate is 2-4 weeks from now.
