The more I see videos, the more I may consider replacing my Aura HD with the Aura (maybe, in the end, after thinking long and large and having hold one in my own hands ...).
Mainly because of the lack of ghosting, the nifty 2-finger swipe and the apparently better rendered PDF documents. The smaller size could be a good point. However, I like very much the high resolution of the Aura HD
One thing though, to protect my Aura HD I always put it face down on the (bedside) table so nothing can touch/scratch the screen. I do the same with the Mini when it's not in its cover or a bag. With no recess on a screen I would worry more, unless this is a Gorilla-glass like strong one
