I really like Google Now. I have the widget to the left of my home screen (in place of the Flipboard). I use it to see how long it will take to get home, to tell me when I should leave for meetings due to traffic, reminders for new shows (it reminded me that The League was on last night, hilarious), package tracking, and score updates. It is actually one of the favorite things with my move from iPhone. Also, "OK Google set my timer for ..." has replaced my kitchen timer.
