Microsoft has just released a couple of ads showing how Cortana  is much more useful then Siri

In the first ad , named Lost  , Cortana looks into the Calendar and inform the user to leave early due to traffic conditions while Siri is still turning on the GPS.

In Remind Me , Cortana ‘intelligently’  reminds the user what to say or ask when a specific person calls,

What do you think of these ads , do let us know in comments
