The feature that's important for me is having immediate physical output. I don't like reading what I just wrote off a small LCD display. And I like having the paper result right away, but it would be nice to have a digital copy if I wanted to edit the document further. But thanks for the lead!
You're missing the digital part. And I don't mean editing typos, I mean real editing. And things like being able to turn it into a blog post, for example.
