I get no pleasure in saying I fully agree with you, ST. I was going to go for the 6S but after seeing and using the S6Edge I realised that actually the bogey man stories of Samsung phones is just that ... made up. Although - it's only in 2015 that Samsung went for quality build and OS ergonomics - previous stuff was too clunky and menu-heavy. IOS started life as the antithesis to that.
Now IOS has ironically become heavy and clunky. The reason I moved TO Apple stuff. Its by no means been an easy transition but the superior camera/software, ease of use and style win me over every time I use it now. Samsung were certainly guilty of plagiarism of their rivals' ideas and products. Now that Apple has taken its eye off the ball for the past two years, they've taken advantage of this and moved into the overtaking lane.
Too many Cooks (sic) spoiling the broth and laurel resting could be a lot of the problem but it's too late to start looking back. Apple needs to rethink why they got where they are. And it wasn't through making Wacom style styluses (Pencil), Turing-test talk-bots (Siri), iPhones on steroids (the iPad Pro) or for that matter iPhones shrunk to pocket size (the Apple Watch) then having the nerve to reinvent them all as something revolutionary. Again.
Let's hope 2016 is the year Apple stopped renovating the old stuff and starte innovating the new stuff.
Yeah baby!
