Neat eye candy, granted. I'm glad so much emphasis went into legibility, and that accessibility variants are baked in.
But I'd still love a modern device with very basic UI. Palm had it nailed, and I had no beef with the basic shapes of Windows 3.11 or colored squares of the NT/XP eras. Buttons, window edges and other controls you can readily distinguish that simply stay out of your way when you don't need them. No need for every pixel to scream out "look at me" when you trail your finger over it.
And I am all for it. After a few days of this new OS, I really like it. It takes a day to train your eyes, but that happens with literally every version of the operating system. But once you do it is so nice for all of the function to just get out of the way.
