as much as there are defectors leaving for android, there are a lot of those defectors leaving android for iOS. as a 4 year android user, i can see why apple is slow to adapt things. because as much as it looks like they are behind, they are actually waiting for the piece of technology to mature or gains widespread support i guess. this can be only said for NFC capabilities. it doesn't work well and comes off as gimmicky at the current moment. many of the features on android are cool though. however i left for iOS because of the poor reliability of the android OS that i have experienced over time. if complacency is going to be the downfall of iOS, instability will be the downfall of Android.
