So, Harmattan is not MeeGo. It's only called MeeGo, but it is still Maemo. It's not MeeGo product, but MeeGo instance.

OK. Got it. Now it's clear.

So, this thread is about creating MeeGo product which contains Harmattan components, on the contrary to MeeGo instance contained in Harmattan.

Understood. It's not confusing anymore.
I was under the impression that Nokia is working on MeeGo product, but they are not. They are working on MeeGo instance and THIS thread is about community created MeeGo product dedicated for N900.

Don't you worry that you will loose audience as soon Nokia launches Harmattan device and starts working on MeeGo device? Similarly to how Mer lost traction once N900 got released.
