Safari
CNN: Apple's new Safari Web browser is based on open-source code that Apple engineers improved on and released back into the public domain. It loads webpages on the Mac two to three times faster than either Microsoft's or Netscape's browsers. It includes a Google search box right in the toolbar and has a nifty snapback button that allows you return to your original search page after you've drilled down a few pages without having to click the back button repeatedly.
