You know, I have an iPhone 6s and an iPad Pro, a Mac Pro, an iMac, a MacBook Air, a new MacBook, and five AppleTVs between my three houses, and I cannot recall the last time I used iTunes for anything, other than peripherally on my devices through its app stores. It had to have been four years ago when I restored my iPhone 5s after I upgraded from my iPhone 5. But even then, iTunes on a Mac is a much nicer experience than on a Windows machine.
My documents are on every one of my machines, totally transparent to me, and I don't need to worry about moving them from one to the other. So why bother? It doesn't matter if any document, music file, photo, video, etc., is on any particular device or on the iCloud, I have access to it wherever I need it, whenever I need it. I don't need to plug in and "move and copy" anything. You guys really just don't grasp the concepts, transparency, and utility of Apple's shared ecosystem at all.
As long as everything in your “ecosystem” is Apple, I’m sure you’re fine. Just don’t try to make Apple “play nicely with others”. It’s a closed, proprietary architecture.
Same here. I don’t get it. I have apple products because they’re simple and just work. No instructions required.
