You're talking about the same company that it took until late 2014 to have a 1080p display on a phone; while almost every other company had it in 2012/early 2013. Along with an "incredible" 1gb of ram with the poorest multitasking system, while other phones have 3gb and much more true multitasking.
Face it, apple doesn't catch up with the times for about 1-2 years with every product. Whether you like them or not, that always holds true. It's brilliant marketing and sales tactic, just like the ipod touch 2nd gen jailbroken was capable of nearly as much as the iPhone 6. Apple doesn't implement new, they implement as old as they can, as long as they can, for as much as they can. That's not to say some of their products aren't great, and that other things about their products sometimes try to make up for these things; but it's still true.
