I believe he wants an open OS so it can be modified. Just because it runs Linux does not mean it can be easily modified. Take the Cybook Gen 3. The OS partition is not user accessible. If you were to build the base OS from source as provided by Bookeen, there is no way to install the result onto the device. Bookeen has also made the firmware upgrade processes very difficult to do anything other than upgrade to another version of their provided firmware. So in the sense an open OS being a modifiable OS this is not a moot point.
