Well I canceled my online order and picked one up in the WHSmiths store, got home fired it up and found I had a couple of black dots on the screen

Don't know if there were dust particles trapped under the plastic top screen or something else. I took the Aura back and got a replacement that looked ok in store (no back dots) got home and noticed two light leakage dots when the screen went to a black screen

So took that one back and had to get a refund as they only had the two in stock, prob not a bad thing considering the QC on these things
I did like the form factor of this device it's like a mini but 6" screen

I also liked the screen changes without the black refresh, I didn't like the plastic feel of the top screen though, just felt cheap.
Looking at my V1 paperwhite and the Aura side by side the text looked better on the PW for some reason, Fonts just looked darker and sharper and the screen looked whiter, might just be the way I had the Aura setup though, I did fiddle about with the settings a bit on the Aura but still preferred the PW.
I won't be getting another Aura I think I'll go for a PW V2 or just wait for something better.
