Personally, I don't like any of the names.

I would prefer something more in line with Meego/Mer as it's the most probable future we can follow and is not disrespectful with the past Maemo. However, before using something Mer-like, we should first negotiate with Mer team.

Now the most important thing is to form a NFP to start funding and transitioning from Nokia, so I will vote for Hildon, as a less bad option. The already existing foundation doesn't have any relation to technology, so I hope it shouldn't be a problem.

Anyway, my guess is that next Board/Council would be able to handle this issue with enough time (and maybe using a real voting/referendum) to change the name if desired/needed.
