This is what happens when you try to make one OS service too different devices. Even if Apple ends up merging iOS with OS X, it's doing so gradually so it doesn't drive the car off a cliff before the engineers have attached the wings.
You have no idea what you are talking about. If users want a wallet garden app store, locked down OS they will use Apple, if they want a Cloud Centric OS they will use Google.
Power Users maybe, but not the masses. I got my mother a new touchy acer laptop. Took all of 5 minutes to get her using the corner for the start button. She like many others focuses on what she wants to do, not how the computer accomplishes that. She has no idea that the Microsoft App Store is a walled garden. It has Skype, it has games. She only got google chrome because I won't support her laptop if she uses "The E".
