Add Cortana voice op for Apple Watch
So you already have the Cortana app for iOS. Add Apple Watch support to that app, then add a complication with a big blue button, like the red button on 'just press record' app, but let it send the voice data straight into the mic button on the Cortana app for iOS. Then BOOM! We have an iOS Cortana solution as easy to use as Siri, but smarter and that will actually work, because it is Cortana.
PLEASE DO THIS! Shazam can do it so can you, would be so useful....
