Sadly I think I would agree with much of what you say. The dreaded beachball of death issue plagues me on Mac too!

I don't have similar issues on Windows 10 - I think this indicates perhaps a shift away from the important user experience issues.

I think you have it spot on when you say Cook is a business man whereas Jobs basically was a physical embodiment of Apple.

The things is they can easily reverse it if they just paid attention to the right things but I suppose they don't see what the issue is.

I too am very tempted to go to Linux - once I can get my favourite apps like Photoshop on it then I think I will try moving over.
