I'm with the people who like the reader bare when reading. So something like a zip sleeve (for only carrying) works. I looked around a bit and the m-edge latitude jacket is listed as made for the newer Kindles, Kobo Touch, and Sony T1. It might not be an exact fit but maybe close enough. The local Staples had one so I might bring in my reader and see how it'll do.

The T1 is the smallest of those readers so would fit worse in any case labeled for all of them. But it might do. Other cases for the newer Kindle:
Belkin Porfolio Sleeve
Belkin Grip Sleeve

Marware jurni Amazon Kindle Cover

The Marware seems not available yet and the Belkins who knows if any store has 'em to try. And there are probably others by lesser known companies.
