Just doesn't seem like a must have upgrade for me.
- iOS in the car: not planning on buying a car in the couple of years.
-iTunes Radio: I'm in Canada, we don't have it yet.
- New Siri input method: underwhelming.
- Shift button enhancements: if the shift button was causing confusion for you, your problems run deeper than a software update.
- Touch ID improvements: I have an iPhone 5, so...next.
-UI refinements: I truly don't care about that sort of thing.
Auto HDR sounds good to me, but that's it.
I'll stay where I am, and one day get my lazy **** around to JB'ng.
