I'm just guessing here, but I suspect that Amazon Voyage sales are already into the tens of thousands. Just look at how much Amazon is having to write off for the failed release of the Fire phones. They are writing off $170 million and have $83 million worth of the phones still in stock, and this is after slashing the price from $200 down to $1 with contract. (According to http://abcnews.go.com/Technology/fir...ry?id=26425329.) I don't know what the Fire was valued at, but let us just say $600, so 83 million divided by 600 equals more than 138,000 Fire phones that didn't sell. I suspect the number is actually higher than that though. And I wouldn't really think Kindles are that much of a niche market now that ebook sales are surpassing paperback sales, and factor in that Amazon has about 75% of the ebook sales market in the USA. But who knows for sure...

Page turns do seem slower to me, but I'm going on memory as I don't have a PW to compare it to. But the increase in resolution means there are a lot more pixels (or whatever they call them on eInk screens) on the V to refresh than were on the PWs. So maybe that takes longer.
