As a public service, I ran a completely unscientific test on a product that sure would look good under any Christmas tree. The words I entered into the search were: “Titanium PowerBook G4 with superdrive”
Here are the results of my product search test:
Froogle: Gives several sources with photo of product, price and link to store.
Yahoo: There are fewer links than Froogle, but it includes a handy “buy it” button to each store. (A business model I can understand.)
Bottom line: Despite my Google prejudice, it appears Yahoo has the better product at present. However, none of the sites I tried gave me a link to the obvious source, Apple.com or to other obvious web super-aggreations of sellers like Amazon.com or eBay.
Another alternative which I consider a better way to find the really good deals is to use another product search tool from Google, their catalog search. The results from the catalog search gave more options and access to low-cost alternative sources.
