"We are not the same ecosystem as Windows Phone and we will use different tech than they did"

I never said you did. You still face the same issues. It's not like an ecosystem succeeds or fails because it chooses a certain language.

"and even if we fail (which I don't think at all), it is part of life, work."

That really does not inspire confidence in the project.

"And for the end user - I don't think community failed, it just didn't have the multibillion dollar marketing machine behind it and also GNU/Linux commercial activities went into server and rarely into end user app, we plan to change this."

I wasn't talking about marketing. I was talking about user-centric design, and usability of the software. And GNU/Linux stuff has largely lagged behind other, product based offerings in these regards.
