My thoughts upgrading from the iPad 3 to the iPad Air 2: The difference in weight and thickness is MUCH more noticeable than I anticipated. It almost feels like an iPad Mini by comparison. This thing is SMOOTH! No delays, no crashing, super fast (AC wireless). I put up with the lagginess of the iPad 3 far too long! The screen is better, loving Touch ID, ability to use Air Drop with my iPhone is huge. Also loving the iPad Smart Case Only negative is the vibration from the speaker, which is a pretty big deal. Some might find this a real deal breaker. I'm probably going to put up with it, given all the other positives and hope they can remedy it through a software update (?). Overall very happy with the upgrade.
