The GRDIII looks like all it's cracked up to be. Very nice shots.
The S90 certainly won't feel as solid, but then again it does let you zoom to ~105mm EFoV (stabilized to boot), which makes it more versatile. The Canon also isn't likely to give you as many options for customization and it probably won't have quite as nice of a lens, nor does it have a hotshoe or as many pixels on its LCD. On the other hand, the Canon gives you basically the same sensor for $270 less. You can even share cheap batteries with SD1200 owners.
Basically the GRD has no direct competition.
While this camera (previous GRD's) is compared to those cameras, none of those are as pocketable, except maybe the LX3 in a large pocket, or the new Canon S90, which even though it doesn't have a fixed lens, it's size and 28/2 starting focal length/aperture make it the GRD's nearest competitor.
Regardless, it feels like a pro camera in a small body. I doubt the Canon can pull of a similar feel and asthetic.
