I am really loving it coming from my iPhone 4. What has surprised me the most is how often I actually use Siri. I use headphones a lot and its so easy to use Siri while wearing them. The added movie and sports functionality is nice to. I am always looking up movie info. The new headphones are actually comfortable and sound good. The camera quality continues to blow me away, along with the speed. Every time I pick it up I love how light it feels; I couldn't imagine having a big bulky case on it. It would ruin the experience. That being said, I am being super careful about handling this iPhone..
