iOS 5 for iPhone and iPad walkthrough

So... how's iOS 5 working for you? Apple opened the gates of update yesterday and unleashed a ton of new software so did you manage to download what you needed? Was it smooth sailing or did you have problems? Did it work out eventually or are you still having issues? Did you update all your iOS devices already or are you waiting on some?

For those of you who've updated successfully to iOS 5, do you like it? Is it what you expected? Are the new features implemented well for you? Anything surprisingly good or surprisingly bad? Any iOS 5 bugs driving you nuts, or hidden gems that just made your day?

One day later and one version ahead, how is iOS 5 working for you?
