If you don’t resend a form you won’t catch the new updates to the site. Plus, it doesn’t open most https:// sites, just a preview of the starting page. Plus, it may hava a fast back button, but it is surely the slowest browser I’ve ever used. If you want to browse the Web, why not just use the Safari that you already have?
