Concerning Bill McEwen I have ambivalent emotions.
At first, don't forget that he did stick to Amiga while Collas disappeared. A good point.
Yet, under his leadership Amiga Inc. had the same PR as before, broken promises, deadlines, announcements, and worse of all, the Microsoft alliance. (Of which the latest may be as well rated as a positive one tho)
I have chosen to care little about him, as in my eyes he is not more Amigan as for example Jim Collas was. (or even less) He has a business to run, I doubt he shares our emotions towards the name and the community.
I don't think he made actions recently which deserve heated attacks upon him. The last time for that was an interview in november/december (can't remember the exact date) stating OS4 will be out in 3 weeks.
As to OS4, and a date of vaporware status.... It's pretty silly, but that is strictly IMHO. I won't declare OS4 as vaporware until discontinuation is officially announced. Timedates (now july) have increased from time to time, usually with intervals ranging from 2 weeks to 2 months, depending on the person making the estimation. This goes on since 2-3 years... If you believe in OS4 don't set up deadlines you have to modify. I still believe OS4 will be reality. People a bit more rational nowadays, only a few believes in a release in 2 weeks, but who cares? It will see the light one day, development is continuous to this day, I see no reason to worry.
Maybe it's a rant, but this is my opinion upon the Amiga Inc/Bill McEwen/OS4 subject.
