Apple doesn't make the best keyboard case for the iPad Pro; Logitech does. It's called the Logitech Combo Touch Keyboard Case and not only is it cheaper than Apple's Smart Keyboard, but it features backlit keys, a rigid kickstand, and all-around protection for the iPad Pro. If you're like me and need a keyboard to make your iPad useable, you're going to want to look into this Logitech keyboard.
