The Ars Technica reviewers opinion
"The keyboard often needs time to catch up to your input.
Tab reloading in Safari is a fact of life, and the constant reloading is something you'll notice even more if you're using iOS 9's new hardware keyboard features and its alt-tab app switcher. There's often just a hint of hesitation for common tasks—pulling up the keyboard, flipping from portrait to landscape, pulling down the notification shade. Again, none of this is new to iOS 9, but iOS 9 doesn't do much to fix it either."
