I may be getting an iPad 3 (from the iPad 2) soon as a hand-me-down, but I don't know if it is worth it for the retina screen and siri, so a couple of questions for those who have used ipad 2 and 3 on iOS 7: 1. Is iOS 7 any choppier and slower on the iPad 3 (or less choppy and slow) due to being retina? Does the A5X fulfill the amount of speed needed for iOS 7 to be at least as smooth as the iPad 2? 2. Is the battery life for average usage (web browsing, email, Facebook, playing some games on 50-75% brightness) less than the iPad 2?
