I have the third generation iPad 3. I recently updated to iOS 7. Everything is actually running pretty smoothly minus this issue. The keyboard displays a .4 sec or so delay when you switch from alphabet set to numbers set. It only does it initially each time you pull the keyboard up. I've tried restarting multiple times. No effect. Recently updated to 7.0.2 and the issue is still there. Is anyone else experiencing this behavior? Aside from that, animations are smooth. No other perceptive slowdowns (aside from perhaps a slightly elongated time delay with wallpapers). Battery life is as good if not better than before.
