My Aura HD got updated yesterday (UK/WHSmith).
Pocket works really great. An awesome bonus I wasn't expecting when I bought it.
It may be a coincident, but the two books I transfered (with Calibre) ended up being epubs and not kepubs. Of about a hundred books it has happened maybe twice before. I disabled the normal driver and it worked fine again.
So far I am very happy with the new firmware. :-)
