For years I've used a 5 years old Canon PowerShot SD880 IS. It received very good reviews and I've been quite happy with it, taking about 45k pics.
Recently I plopped down the dough to get the 'latest and greatest' P&S cam, the Sony DSC RX-100, which has been getting glowing reviews.
On Sunday I played Lu Lu and took both cams out and tried to shoot very similar shots within seconds of one another with both cams. I imported the photos to iPhoto and organized them. Except for maybe one pic I straightened and cropped, the rest are straight from the cams. The Sony can shoot in raw mode, but I'm not doing that yet. I also did no post-processing of the pics on iPhoto. I used Galerie again to build the web photo album where the compression of the jpg's is set at a value of 60.
In the web page below, the pics are labeled as being from Camera A or Camera B.
Is it clear that one camera is superior to the other, at least on this day where both were set to full auto modes?

If you desire slightly smaller versions, use this link instead:
