That is what I am looking at getting....the G15. I have gone back and forth between the G15 and the Sony RX100, but I think the G15 is winning out.
I have a DSLR but want a carry around camera that has many of the features of a DSLR. My DSLR is bulky and heavy and doesn't have video (Canon 40d). I really should sell it.
A friend of mine just got the Nikon 3100 for similar reason (size plus manual/auto options).
GL camera shopping!
