a limit towards features? Like people thought the camera couldn't really get better and that being higher than 8MP would make no sense even if the lens were bigger and also no one EVER thought that the iPhone would have a finger print scanner and when there were rumors people were saying how on earth would Apple include such feature when it would take 5 seconds to read your fingers and lack of space too? But Apple did an excellent job for having touch ID and it works instantly while also being very accurate and same with the iPhone 6 Plus...no one ever thought that Apple was going to release two different iPhone with large screens. Also Apple Pay....A feature that is changing the way people buy things. Another thing some people thought would be a failure. NFC done right. NFC was a failure before Apple began putting it on the iPhone with their personal touch. Apple is just beginning...They have MANY features/surprises left to add to the iPhone. Enough for at least 8 more years of innovation. After that...it will just be minor updates but they still have surprises left. Touch ID/Apple Pay/Plus was not something people expected.
