I don't doubt that at all. This is my second reader I've sent for repair. The first experience went much easier (as the diagnosis was not a mystery), and I had my reader back in 7 days. But I will not be able to reclaim any of the notes I made, and that's the heartbreaker. It's just the most awful (or to the universe, the funniest) timing ever.
I'm sorry your prs 650 has taken so long. I've noticed that there are alot of unhappy forum posts regarding this device. In a way the option of a removable memory is nice, but I'm unsure as to whether this would protect notes/collections made. Either way, considering I've had to send more than one reader back despite making the original purchase Sep 30 I'm glad I chose not to invest in a 650. I hope you get a more reliable replacement soon!
