Yes.
As I said, I called the Sony Style store and a bunch of the Borders in my area (from the dealer locator). I was just seeing if anyone had better luck than I did.
The Sony Store had a definitive answer, but some of the Borders' employees answers to my queries seemed...ambiguous, as if they were either downright clueless ("We don't have an electronics department) or merely confused ("We have a Sony Reader listed...but I don't think we have any.")
I was hoping someone else got luckier with an informed Borders employee.
