GX1 (w/2omm?) ?
having the GX1 with the PZ14-42 I can confirm it's very pocketable (litterly).
The IQ is OK, though the PZ has some limitations (see DPReview GX1 review).
The body is very customisable wrt. button behavior, so it should be OK for your liking.
The LCD is fixed saving space but be aware it might limit candid shooting.
