Not as in depth an answer as I was hoping for. You do realize there's no tangible gain there.
No doubt there are a bunch of design elements, cues, whatever you want to call them that have been lifted from one manufacturer to another and yes, Samsung is a prime example. They did, however, have the rounded design - used by the iPhone 6, in 2012 on their Ativ models.
Who influenced, borrowed, or copied who? Who cares?
Jony's lamenting has become tedious. Every great artist (I consider designers artists as well as technicians) has had their work imitated; it's the way of the artistic world. Everything is an amalgam of what's come before or what has provided inspiration. Hell, if John Bonham and Steward Copeland heard my drumming they'd sue my butt off...
Nothing personal but when I read such dogmatic missives about companies it just strikes me as, dare I say, sad.
The ATIV copied the iPod Touch.
