Hmm.. it doesn't work on Xournal on my N810. Do you just open the .esj file directly on Xournal for windows? (Without converting first?) There isn't a Xournal for Mac, so my little linux tablet is the only device I've tried for compatibility. I also couldn't get my N810's journal files to open on the edge.

Luntz's onenote conversion looks awesome, but I don't use Onenote. Ideally, I'd like my "journal"-y file to be able to open on all my devices as a journal-y file.
