I would be amazed if the "slightly smooth" image of the W1 could actually be worse in detail than an earlier generation Kodak 2MP camera....surely not.
Have a look at the sample images on this site from the reviews. Download any two of the same subject and see how much sharper/more detailed the Sony looks.
I've taken a section of the W1 and DC290 Marina Bar image and cropped/set it to the same size, but without any other manipulation.
The Sony is below, Kodak on the next post.
