Thank you both for your replies. Unfortunately need doesn't come into it, i'm a bit of an ereader fiend
I've had my Paperwhite over a year and tbh i never contemplated a KOBO until the Paperwhite 2 came out, which I really don't like. Then the Cloud Collections update, and suddenly Kindle doesn't seem to be it for me anymore.
I got my AURA for Pocket, and its size and weight, it does have pin holes but I really like it, so now I'm 'debating' about the AURA HD. I'd hate for the 'limited' run to finish and I'll have missed it
