One of my fav features of Safari, we all have one I'm sure, is that it uses the OS's built-in spell checker. I use a lot of sites, lis this one, where I enter a lot of info and a spell checker is my savior. Though I appreaciate the work here I also want software I use to support the unique features of the OS I've chosen. Firefox fails at that. From the UI widgets to support of a lot of services I have to say it wll remain my backup browser for the few odd sites that Safari has trouble with.
