The beauty of the home button is that you can quickly access your "home" page when you are already logged on to the internet at some "other" website. It's one thing to go into your settings and have it "Open a specific page or set of pages" BUT when you are already logged into the internet and wish to return to your "home page" rather than closing and re-opening your browser, you simply click on the home button. Not have a home button, the next best thing is either the extension mentioned by 133t4opera OR bookmarking your home page on your QAB.
