Pros:
* #caldav and #carddav built into the system
* The measuring app is pretty neat.
Cons:
* RFC 6186 config not supported in mail app? (apple wrote this spec?!)
* Can't download apps without an apple ID
* Apple news is enabled by default
* Can't sideload apps without an apple ID (I considered #altstore)
* Can't use GPS without agreeing to give location to apple.
* Couldn't jailbreak due to previous owner leaving auto-updates on.
* safari JS toggle is all-or-nothing
