Powershot S90 user here. Clearly pocketable and decent image quality.

Canon PowerShot A620 in my case. Similarly pocketable and very good for holiday photos. No RAW, and IQ deteriorates when pushed to any limits. Not up to G9/G12 standards, but less than half the price. It is almost always with me, in a side-pocket on my shoulder/shopping bag. Will fit a jacket or trouser pocket for parties, functions, etc
In my younger days I had a lovely Kodak Retina II 35mm, which was my father's cast-off. Folding bellows rangefinder, neat and small enough to fit into a pocket, with a good fast lens. Alas, someone begged the loan of it from me, years ago, and that was the last I saw of it :-(
