Well that's an ironic statement as it's like you started disliking apple after 2011.
The 5S was released in 2013 under TCs' watch and featured an array of game changers; touch id (mentioned), 64 bit, m7 corprocessor, slo-mo, true tone flash, plus more.
The 6 was a game changer for a larger size and apple pay, and by the way the sales of the 6 reflected that. The 6s was a complete under the cover over haul and the gold award and sales reflected that.
The 5/5S were probably the last couple of iPhones that Steve had any sort of involvement with. I truly believe that the 5's form factor was Steve's "compromise" of sorts in terms of responding to the demand of larger displays. It was only slightly taller and at the time, Apple was completely spot on about it being the ideal screen size for your thumb usage but look how quickly they changed their tune.
The 5S was a solid and substantial upgrade to the iPhone 5, but not a game changer. Touch ID is a really great feature, but stop acting as if Apple invented fingerprint scanner for smartphones. As for the internals, obviously were top-notch back in 2013, but the truth of the matter is, that's not what drew people to buy this, most were just upgrading from their 2-year-old 4S and simply needed a new iPhone, not an indicator of anything other than a normal upgrade cycle,
I really don't understand how you can downplay the significance of the iPhone 4. It really was the biggest leap in innovation with the iPhone since the original. Like I said, everything that we take for granted with iOS devices were introduced with the iPhone 4: Retina Display, FaceTime, HD video recording, A-series chips and its industrial design. That is what I would consider to be revolutionary, the iPhone was still ahead of the game at the time but everything afterwards has been evolutionary.
The 6/6 Plus is a product of market demand, it was inevitable that Apple would cave in and release bigger iPhones to compete with Android phones. Again, stop acting like Apple made the first smartphones with 4.7" and 5.5" displays. Samsung, HTC, etc. have already been there and done that and then some. Apple Pay, a decent service is also nothing special and didn't exactly catch on the way Apple would've hoped.
As for starting to dislike Apple after 2011, I never said dislike them, I'm still very much a Mac user but as soon as they started making really stupid decisions and half-assed product releases, I started to lose some of my respect for them. In some ways, Tim Cook is desperate to prove himself by doing the exact opposite of what Steve would've done. And in some cases, it's quite obvious that Cook has done a lot of things to Apple that would infuriate Jobs and make him question if he truly chose a worthy successor.
And every single time you keep citing the sales figures, you just continue to prove my point that Apple has become way more profit-driven (as opposed to making the best possible products) under Cook. Your fanboyism doesn't seem to tell the difference between quality and quantity.
Also, when has any iPhone ever gotten a bad review? I'm not saying all of them are paid off by Apple (although Mossberg is most definitely in bed with them) but there's obviously a bias. That doesn't mean they were wrong in their lauding of each iPhone generation but guess what, they're not the only devices that get praise from tech critics so it ultimately doesn't mean much.
