I completely agree with you. I am not going to stop using ubuntu, but what i am saying is this is not an act of maturity. we love Linux for the Base context of being free and open source which is not going to change. The Reason for not getting picked up i assume is the constant UI changes Ubuntu is doing. well i did't actually like the UNITY Desktop. What if they could have just maintained a sleek UI and added more and more nice features. I hope that would have helped.
