Just paid a visit to Appshopper.com in order to find that there are at least 3 new Safari "replacements" just popped out. (Big Browser and Best Browser are esssentially the same, what gives?) Are they all just Safari with alternate layout engine?
and there is no search history on most of them so if you don't want a certain someone to see what you've been searching then those are for you, i personally don't think they have a purpose just stick with safari....
