Today when i ended navigation from the lock screen i almost screamed out in joy. Later i discovered some new music from a great playlist i would have never found in the old terrible music app. I later checked the news from the lockscreen, checked my calendar from the lock screen, and replyed to some texts without unlocking. If you think none of that is useful then Im not sure what else they can do for you.
There's more to life than doing regular stuff from the lock screen
