While most of the web is free to access through any browser you'd like, there are occasionally websites (particularly older ones) that need you to use browsers like Internet Explorer, or worse yet, would like you to be on a Windows PC.

Whether you develop for the web and need to see how your site or web app displays itself in multiple browsers, or you just want to visit a site that requires a particular browser that you don't want to use, you may eventually need to use a browser other than Safari.
