I've just ordered an X10 to replace my frustrating S90 (slow focus, high noise, fiddly controls, no viewfinder). The improvement in pocket cameras over the last 5 years has been quite disappointing. Not interested in ultimate resolution from a pocket camera - just want good images for more than static subjects in good light.
i need to see more development of the mirrorless interchangeable systems before commiting - there's not a pocketable (even for big pocket) choice with built-in EVF, and the IQ of available camera/lens combinations can't persuade me to leave the 5D2 at home for reasonably serious shooting.
We'll see.
