iPad Air is a great product and the best tablet out there (my opinion)...BUT its overall smoothness in UI navigation in iOS 7.1 needs some improvements. For example, rotation animation in the App store is awful (not smooth at all). The same goes for rotation whenever the keyboard is displayed (although not that awful)... It definitely isn't on par with iPhone 5s or even iPhone 5. Try those things for yourselves. Does it bother or annoy you? PS All the transparency effects must be turned ON (so turn off "Increase contrast").
