So far I am very happy and hope that trend continues. All the good Stuff 1. Exchange is working 100%, cal, email and to do lists with outlook 2013. 2. iMessage all up and 100% 3. Internet fast 4. WiFi connection no issue. 5. Screen size and quality all great 6. Main reason for the jump was iP5 battery was dwindling. 7. Calls are clear 8. Touch ID is great for me. Things that need working out: 1. Screen has a noticeable delay on rotation? 2. Has hiccupped a few times with Bluetooth connection to my car (2013 Infiniti). A re start clear all issues. Only happens 5% of the time. Spoke to dealer, I am not alone. 3. some safari pages are hard to navigate, I liked the back button on the bottom when I tapped screen. Not as easy to page back.
