I don't have an Aura in front of me, so excuse me for the weird question. Isn't the Aura's screen longer and larger? Because by what I can read in this thread, many people complaining of having a bigger device but not seeing much on the screen, I would guess the bigger size is only one way
I am considering buying one when it will be available, but not for the bigger screen (I'm very fine with a 5 inch screen) mostly for the crisper display. Slightly off topic, I know, this one is for a firmware version.
