Got mine today, after about 3 hours of screwing around with iTunes I finally got it working. Guess iTunes needed a update. After the update it kept crashing. Figured out it was my external monitor, so I disabled the driver. Got it working and finally got everything transferred over.

Hard to say if the battery life is better or worse. I'll know more this weekend. The fingerprint deal is gonna come in handy for iTunes. No more typing in my password, just swipe and pay 😳😁
