Interesting. A Java based reader makes it more likely that the reader will continue to work even if existing platforms expire, though if I understand correctly, Mobipocket only allows you to have up to four devices activated at once, and sets the device ID for only the activated devices when the eBooks are downloaded. I wonder how the device ID will be set for the iLiad? Does it have a software-accessable serial number?

Mobipocket's prices aren't that great when you consider they still hold your content hostage. You get maybe a dollar off paperback prices at best, and if they fold or don't support a future system, you can't read your content anymore. Of all DRM systems, I still think the "least evil" is probably eReader/Palm Digital Media, which uses your credit card number as the key. Too bad they don't have a Java version.
