Ubuntu are trying for ease-of-use and it's a noble goal. But if you are going to judge them only on ease-of-use, then it is difficult for them to compete with the resources of Apple, who are the richest company on the planet.

My point was that there are quality open-source projects out there, after you appeared to assert otherwise. But ease-of-use is not something developers/startups seem to be interested in spending time on.

If you want me to qualify stable, then let's compare Apple's bidirectional iCloud sync to Unison, or Time Machine to ZFS snapshots.
