I said that I really like using Cortana on my Windows 8.1 phone but now I am really looking forward to Cortana on Windows Phone 10.

Microsoft made some very exciting announcements at the the Build conference which make the future for Windows on every platform look quite good again. But also, they talked a bit about Cortana as well. It is not news, but they confirmed that it is going to be very easy for developers to integrate Cortana with their apps. So she will be able to handle in-app commands without having to open the app and display its UI.
Watch Joe Belfiore’s talk about it here.

I love it!
