I have had each iPhone since its inception and with each release I was excited for it to be delivered and mess with the new features. Original iPhone - Touch Screen iPhone 3G - App Store iPhone 3GS - Video Camera iPhone 4 - Retina Display iPhone 4S - Siri iPhone 5 - Bigger Screen But the last couple of releases I have enjoyed my iPhone but didn't really feel that spark or excitement. Sure the features were cool, but after a few hours I was ehh, its a phone again. But with the iPhone 5s its a different story. There is two features of the 5s that continue to amaze me! First, the Touch ID I use all the time and find my self trying to use it on my iPad Mini. I figured it would be a gimmicky or awkward feature like Siri (beta). But it honestly feels like its my first time using the Touch ID each time I do it, there is something about it that just seems like it should have been here since the very beginning. Second is the Slow Motion Camera, another feature I thought was going to be gimmicky and something I wouldn't use. That was until I used it, the simplicity behind it and the content I can create! I literally spent half the afternoon slow motion filming my dog in the back yard.... Personally I think Apple took everything from the previous 5 iPhones and made one AMAZING product! - One happy buyer! Which iPhone is your favorite ?
