Anyway, it's interesting how many GNU/Linux to -> Android OS, applications "migrations" are happening these days which again shows the close relationship (well there are apparent differences) between the two parties.
It is developed by as a Launchpad project and according to them the aim is simple... quoting their own words below,
"The aim of this project is to bring the same goodness to the Android platform. The goal is to be file format compatible and be able to sync notes with tomboy. Of course, keeping a great UI adapted to the mobile context is also a goal of this project."
Still it's at beta stage it seems, and only supports read-only at this time. But that's for a short while without a doubt. You can sync your date using Ubuntu One or Tomboy online accounts as well. Wanna give it a try? :).
