The distribution should be "consumer" friendly, in installation and in service; and have some sort of "market place" (ie GUI frontend to big local package repo, or application manager etc).

I have recently tried Unity and polished unity looks pretty good.

But with current Ubuntu policy of
1) "we want to control everything", ie "Mir" case
2) "we require CLA everywhere", ie can turn all into closed source
sure people will search for alternative.

Please suggest and explain why(strong points, weak points).
