It's convinent only in a sense that you dont have to re-download all the apps but it doesn't carry over the app data(so games that doesnt have log in in other forms all process is gone) or browser used so unless you have snyced need to be moved manual. All messengers needs relogging in which I don't mind for most since it has google backup but not possible if you trying to get your line chat history from iphone... What good is connecting to Icloud but not being back to restore chat history...
