I run/hike/bike/ski/etc, with a Canon S95, and I sometimes use my old SD 1100 as a backup. I also have a G9, but I favor the S95 since it has many of the same capabilities.
The S95 is a bit on the heavy side for running, but the optics are crystal-clear, it shoots in RAW mode (basically = lots of range of lights and darks), and has manual focus among other features.
I adjust the images in Adobe Lightroom afterwards. Rather than editing the original image, it keeps track of your changes and only applies them when you export ("non-destructive" editing). Its interface took a while to get used to, but now I use it almost exclisively. It also contains a catalog to store the edited images tagged with keywords.
Some Canon models that I've owned and liked:
For me the image clarity is the thing, and in general I've liked the look of Canon ELPH images. With a few exceptions, other brands look fuzzy to me. Some Canon models that I've tried and found the images too blurry compared to prior models:
- Some Panasonic Lumix image are nice.
- Some of the Sony TX images are nice.
