Inexpensive reader cover
I picked up a notepad folio (5.5 x 8.5) from Wal-mart for $8. Put a couple of strips of Velcro along the back on my reader and the folio. So for about $10 I got my reader protected and full access to all button and the usb port.
Just a thought and to me it beats that sleeve thing Kobo is trying to sell.
