@Takemehomegrandma,
I agree with most of your assessment, but would add that many Amiga users are excited about the Natami project precisely for the reasons you stated that they are disappointed with all of the NG Amiga-Like systems. They see the Natami as a chance for getting an evolved Amiga system, instead of, as you put it, an Orange with a bit, or a lot of Apple flavoring added. ( Edit: #2, In re-reading your post I think this is in line with what you were saying, as I somehow completely missed your inclusion of the Natami project in my first reading of your post, so I think we are on the same page.)
Now, it is yet to be seen if the Natami team will be successful in creating a system and OS improvements that will be generally accepted as an evolved Amiga system, but they appear to have a good chance of succeeding in that regard, if/when they can finally get their ambitious project completed.
Edit: I would also disagree that "Apple", the company, actually evolved their OS. They just did a more thorough and complete job of adding the Apple flavor to their Orange when they moved from MacOS9 to MacOSX.
