The new card deck like tabs in Safari on ios7 , is that feature only for iPhones? (Also the disappearence of the search/address bar on scrolling down?). I am not observing these features after upgrading to ios7 on my ipad 3rd gen.
The card deck tabs are only on the iPhone and the iPod Touch, not the iPad.
The search field is built into the URL field. Just start typing in the URL field and search results will appear on the page and you can see "On this Page" - further down from the search results if you want to search for a word or phrase on the page.
