The iPhone 6 Plus breaks a lot of the rules and defies a lot of the logic that Apple has stuck to for a number of years. It’s a copycat device.
It chases a market that the company did not create for itself, it introduces fragmentation in a previously restrained product lineup, and it doesn’t immediately give you the sense that you need to own one. In short, it’s the most un-Apple-like Apple product we’ve seen in a very, very long time.
The famously selective company(many would call it arrogant) repeatedly dismissed and even ridiculed the idea of outsized smartphones for many years; defying industry trends and sticking with a smaller shape that was easy to use in one hand despite an obvious shift in the market. In the past.
Apple has been defined by its refusal to participate in such "bubble" markets and has instead created its own - it suffered endless criticism for being the only PC manufacturer to never have offered a netbook, but then proceeded to destroy that entire product category by introducing the iPad and defining the future of touch-first portable devices.
