I really don't like the idea of having to swipe up from the bottom to access the nav bar. Sounds pretty inconvenient. I am not sure if they have really discussed it anywhere, but does that mean you cant access Cortana voice controls without swiping up from the bottom and hitting the button? I usually use cortana when im driving and cant actually look at my phone (I just know where the button is). Adding another step doesn't make that any easier.
I know there is a cover that has it integrated in, but not everyone will have the cover.
