i've taken the s90 nordic skiing in the jacket pocket or fanny pack - it does well in good light (distortions processed in LR3) and really is a pocket camera. the aftermarket grip helps a lot, the controls are a bit fiddly
to spend more money than the s95 and have it not go conveniently in a pocket, i'd go for micro 4/3 - better resolution and high iso performance - and much more flexibility - at a price
