True, but the problem is:
1) Have they refined cloud services? (iCloud is pathetic)
2) Have they refined smartphones? (see iPhone 7 rumors; iPhone is still great but pretty soon Samsung will dance around it)
3) Have they refined desktops? (see pathetic MacMini, and Mac Pro. I give you that iMac is still pretty great)
4) Have they refined laptops? (see the pathetic MBP line. MB is nice but for $1,700 is not that great as a refinement)
5) Have they refined smart watches? (I think they are on track for something, but they're focusing too much on the bands, and it's hardly a revolutionary product)
6) Have they refined music streaming service? (Apple Music... please...)
7) Have they refined the television? (I love my ATV4, but it's far from being a revolutionary product. Granted, the TV industry IS the bottom line problem).
8) Have they refined Operating Systems? (Up to a little bit ago, yes. I think iOS and OS X are still the best around, but we're seeing an increasing number of issues).
...Not to sound like a fan boy, but you are naming situations that happened under Cook. Cooks problem is he keeps trying to invent, not reinvent, rethink, and "think different".
Edit: I also do not disagree with you on any of these points. The lineup has become cumbersome. Steve's main thing was focus and not copy anyone else. Apple keeps trying to be something its not. It needs to refocus on what it's good at. Focus on what sucks in other products, reinvent them to become the template for other companies to rip off - and most of all, make it simple, simple, simple.
Your points:
1) iCloud is Pathetic. What is it? A google copy? A dropbox? What is it trying to be?
2) In my opinion yes they have, although I do think no body style change is suicide.
3)No; but iMac is fantastic.
4) Not at all. Customers are not buying them either if you look at their latest report.
5) No. Terrible UI, Slow, Feels clunky and is a useless add on product.
6) No. Terrible UI, Slow, Feels Clunky.
7) No. Absolutely not - Playstation Vue is the king of this.
8) Yes.
