Well, the good news is you can't really go wrong. As I think was noted in your first thread, reviews by the unwashed masses should generally be taken with large grains of salt. (Large, like the ones put out for cattle to lick.) Your own creativity and skill level will have a far greater impact on the quality of your pictures than any feature difference in cameras currently on the market.
David Pogue wrote a few articles on his nytimes blog arguing against the megapixel myth, which included making 16x24 inch test prints and challenging people to tell the difference (they're generally indistinguishable unless you are doing massive cropping). So, for me anything beyond 6 MP is plenty.
A few years back I purchased the SD780 based on it being pretty much the smallest camera in the Canon lineup. When I want more features, I go to my Nikon SLRs, but as the saying goes, the best camera is the one that's with you. If this is your only camera, you may want more features.
Now, none of the above may have been particularly helpful in making your decision, so here's something that might:
Given that camera and lens quality is "more than good enough", I would consider the most useful feature on a compact to be the exposure compensation adjustment. The second most useful feature, one that many compacts don't have, is a flash compensation adjustment. Leaving everything else on auto, and just adjusting those, should give you the best control over your shots.
