I have an e-inkling (see what I done there) that the upcoming update will only feature annotation in .txt, .htxt and .html or just a standalone note-taking application. Take a look at the link below http://www.vialeon.com/documents/manuals/N526-English%20Manual-20090929.pdf pages 13 and 16-17. May hint as this device is device is just a touch-screen version of the 511EB.
