And thanks for passing along the example of Sears…]]>
Apple is a good example of a Product Site with much more info about the product.
An Exception to the Idea that Product sites wouldn't show competition:
Sears.com shows both their brands (Kenmore, Craftsmen…) along with the competition.
Obviously Sears has to sell competitor's products, but it does show some guts because their brands are right up against other big names.
Also, Sears does publish (or used to) negative user reviews of their products. Also not common.
(Otherwise it is not a particularly well designed site).
