>>2891229I have the X100. It's portable for sure, but not pocketable at all (unless its a large coat)
I hear the Ricoh GR (digital) are fairly comparable. Never used one, but look as though they would fit into a pocket. People seem to like them for shooting street if thats your thing. There's a few different version of them, I think the 16megapixel being the newest, and the 12MP being the generation before.
FYI - Picture shot in x100.
