Previously had 3G,3GS,4,5 so this is the longest I've a particular model.
Is the same stagnation in Android land too? I wonder how manufacturers will handle it in the long run?
I think what people mean when they say this is they are used to Apple redesigning the outside of the phone every 2 years. I just do not see that as necessary. Unfortunately, many people care more about the superficial it looks different instead of the real improvements which it had many.
I don't really think my Pixel is amazingly faster compared to my old Nexus 5, most apps I use on a frequent basis were instant on both phones. I think the screen is arguably worse on the Pixel but unless I go find a Nexus to compare with, they're essentially identical.
The comparison of the 7 and 6S between email, browser, twitter and a couple other common apps however is negligible.
As long as this is an industry-wide problem, Apple has nothing to fear. It would be a problem IF people who have waited three years to change their iPhone decide to go for a different brand.
