I disagree...
You are the exception, not the rule. Most people our age hate change. I even experience 20 and 30 somethings that hate change. So, he is absolutely correct in his assessment of the masses not the few and far between.
I disagree with your assessment of Unity as well. I think it's headed in the right direction but it isn't absolutely perfect. Nothing is. But things have been simplified for the most part. I can't say for sure but I think they're trying to use the best of Windows and OSX to try to come up with the ultimate interface. Not a bad approach if they are doing this. I see a lot of similarities with Unity and OSX.
I don't know what your definition of limited success is but Apple has done pretty well and they still aren't accepted into the enterprise for the most part.
It would probably be a lot better if the developers would announce their intentions and try to let people understand what they were thinking. But since we really don't know what they were thinking then maybe we're missing out on some critical info that would help us understand why they are doing some of the things they are doing.
