I ended up skipping over the Canon S95, but when Canon launched the S100 the features made contemplating a switch compelling:
- Integrated GPS, so no awkward geo-coding hassles lining up the Edge 800 with the Canon.
- 1080p Video. With Bowen's arrival, I found myself shooting video. Some of it is even viewable.
- 12 Megapixels while preserving low light performance. More resolution means you can crop more and still have enough leftover for usable pictures. I've never been satisfied by the quality of digital images short of the .Canon 5D Mark II's. The S100's sensor stays the same size, so raising the number of pixels could add more noise, but Canon claimed that this wasn't so.
- 24mm->120mm higher zoom range. At the long end it didn't matter very much. However, the wide end is very attractive. The 24mm end of the 24-105/4L is one of my favorite focal lengths. Having it on a point and shoot makes photos coming out of it extra special.
