Safari is getting a huge update with iOS 5, which will include a new Reading List for later reading of interesting articles, tabbed browsing (finally!) and Safari Reader for a distraction-free view of the webpage or article you're reading.
Reading List is a huge addition, letting users save an interesting article for later, much akin to Read It Later or Instapaper. Just tap the Reading List button and you're presented with all the articles you've recently saved.
Tabbed browsing is just how you'd expect it to be in Safari, with a look and feel the same as Safari on Mac OS X. This is a much-welcomed addition.
