canon S90, very good, pretty small, G11, etc are a little too large IMHO (I had a G9, sold it – too large and a little too noisy, the G11 is bigger again) . . . recently bought an S90 as a go everywhere camera when my SLR is too much hassle to carry. S90 has the same sensor as the G11 and is certainly a step up from the G9 I had in sensor noise, all the manual modes you need, decent zoom range, raw output that is properly supported in general RAW processing tools (unlike many of the panasonics).
I shoot a lot of images on my D3, but I still have a place for a back of the jeans pocket compact . . .
