Cortana

Cortona is really powerful - I did a test with Cortona, Siri and Shazam. I played different songs and tested to see who picked the song correctly. While my test had no statistical relevance, Cortana outperformed. It is great to see Cortona as an app instead of just a feature on a Windows mobile phone.

Microsoft's answer to Siri and Alexa, Cortana, is now available to download on iOS. Interesting to continue to see Microsoft bring all their apps out across platforms but wether this will tempt people away from Siri remains to be seen....

MS is supporting the NORAD Tracks Santa http://www.noradsanta.org with support within Cortana. Ask Cortana where Santa is.

In my opinion, It's the best one! :)

Interesting. Still hard to compete with Google Now which has been on the iPhone for a while and seems to get the job done.

Isn't it great how Microsoft launches apps that end up forcing innovation to move faster? Excited to see Apple's response

The reminders are the best part. You can set reminders for when you get to or leave a location. Extremely helpful
