Just because another has it first and Apple added it after doesn't mean they copied.
Lol. But when Apple has it first, everyone else copied them. Notice how iOS 7 changed the UI to copy Android?
We'd never get anywhere otherwise. I know Apple take longer but they get things right. Like performance for example. The 6s obliterates the Note7 and its 12 months older.
In what way does the 6s obliterate the note? The note is a much better piece of hardware in every way. Like you, I very much prefer iOS, but as a piece of hardware, the Note7 absolutely embarrasses Timmy and the iPhone 6s.
