At first, Dowser seems like a simple search engine, but then you realize that with the power of Google, wikipedia and sourceforge (pretty sure you can add others) you get an enhanced search exerience running saved results on your computer.
Not only are your searches saved, but related topics get recommended in the flow and you can easily browse back through search terms as well as related topics — kind of similar to A9 actually, but in more simple terms. Pages referenced in results are also cached which is very slick. You might miss some pages as you initially search or decide to go back and try to dig deeper on things and you’ve got a very handy reference of everything sitting and waiting for you right on your own computer. Cached pages let you know when they were saved so you can easily see if you need to check for more recent updates.
Dowser is definitely a keeper in my book.
