Sites like catalog.im and BookFusion.com seems to offer sync of notes/read status etc, but I guess there's no way to push/pull that to/from a dedicated reader (eInk) device? (Except use a web browser on the device -- which I assume is not optimal.)
How about's Sony T2's sync with Evernote? Does it work well? Is it easy to upload/fetch notes or highlights?
How about bookmarks and/or read status/furthest page read?
