  1. Forgot your friend’s birthday?
    Cortana reminds you just in time.

    Cortana is the only digital assistant
    with people based reminders that link
    to calls, texts and emails. So you can get
    a reminder to wish your friend a happy
    birthday before picking up his call.

    With Siri, you don’t get reminders with
    incoming texts, calls or emails, so
    when you forget you’ll have to call him
    back with an apology.

  2. Tired of running late? Cortana looks out for you.

    Cortana’s traffic alerts keep you on
    schedule. When the traffic is crawling,
    she'll let you know to leave early for
    your next appointment.

    With Siri, you’ll have to remember to
    check the traffic and directions before
    you leave. Hope you’ve left enough time!

  3. Need milk on the way home? Let Cortana remind you.

    Cortana’s location based reminders
    pop up when you are close to the store.
    She’ll remind you about the milk and
    to pick up your dry-cleaning next door.
    It feels good to walk through the door
    with everything in hand.

    With Siri, you’ll have to remember to
    check through all of your reminders. Not
    convenient when you are on the road.
