Same here. Looks like great hardware and I even had a pre-order, but I canceled it in part over concern there wouldn't be much of a third party application ecosystem and I'd mainly be restricted to notetaking and viewing/annotating PDF's. I recognize for lots of people note-taking alone is enough to justify it; I just realized I'd personally get more utility out of an iPad or similar.

If I'd seen the "open-source" pitch it might have enticed me to stay onboard.
