Why will the Prime have a 4.65" Screen?

Dunno, but the camera app doesn't utilize the navbar. That's not a good sign.

If the Nav bar at the bottom can not be used by apps such as videos, photos and maps, it really defeats the idea of using a screen for navigation. I am liking what I see of the GN but this would be a massive let down if true. Advertising the screen as 4.65" would actually be deceptive. Please god I hope the nav bar can be used for apps!
