The Logitech Pro definitely makes the entire package more book-like, and it also only has one angle setting AND it does not support portrait mode. Those are the only knocks against it, though. I love the keyboard. I use my Note PRO 12.2 for work and having a keyboard every bit as good as a laptop's is the critical feature for me.
The only thing I'm struggling with is trying to remap the hotkeys to my preferred apps. I want the internet key to launch Habit Browser not stock browser, for example. I know it's doable but I haven't had time to really grapple with it.
