A9.
Once upon a time there was a tiny little company named Amazon.com. Well, this little company took Google results, Amazon results, and Alexa results and smushed them all together and called it A9….
You are welcomed with a nice basic search box. The results screen defaults to web results. A cool feature is if you hover over each result's “Site Info” button, you get a pop-up with some basic info about the site. If you actually click on the button, you get this information plus a screen shot.
There are vertical tabs on the right for Book Search results (from Amazon, go figure) and a Search History tab, which is kind of nice. I think the layout is rather simple and easy to use. There are other nifty features you might want to check out, such as the ability to run a query right from your Address bar (try http://www.a9.com/pet shop boys) and a generic version of the site that doesn't cookie you (http://generic.a9.com).
