The unfortunate thing about Kindle replacements, even for brand new items, is that they reserve the right to send you a refurbished unit. So you might be getting someone else's returned item. I had to get two replacements for my K2 before I got one that was good. And after the first replacement didn't work well, I demanded a brand new unit rather than a refurbished one. It took a while to get them to do that, but eventually a higher level manager approved it.
