The Sony - tiny (exactly the same size as the Canon S95, which should in turn be the same size as the S110), but with a sensor that provides near-APS-C quality, including low light performance. By far the best point-and-shoot I've ever used and as far as I know it's still without a serious rival. (I've not used one, but I assume the Sony RX-1, with its full-frame sensor, is much better still, but to me $2800 seems a bit much for a camera with a non-interchangeable prime lens.)
That RX-1 is quite impressive. Pocket monster.
It's very nice to shoot with and I enjoy it very much(see pic below).
@ Op - You want want to try Fuji X100s. IQ is very good.
