If it's less than the price of my first Kindle 2 (U.S.) with the charging cover (and indeed has a flexible substrate); I might be in. That happens to be how overdue I am for a new eink reader, as well.
We'll see. It's been a long time since I've had to convert ebooks TO a Kindle format. I much prefer buying and reading epubs. For workflow/simplicity reasons (as well as reading app preference)... not idealistic ones.
