I feel the same way. My wife took my broken red 505 in as an exchange for the 650, and my red 650 looks significantly more pink than the 505 did. I'm a bit disappointed as I was very frustrated that 300 pocket was sold in "Rose" rather than red. I was hoping for the same red.
My reader also doesn't read properly in the Sony Reader App. I hand loaded a book on it. But haven't updated to the newest reader Library software, so I figured that was it. I guess I'll need to call Sony. Not sure if I'm going to switch colors.
