Microsoft deal with Cyanogen includes Cortana integration, too
Cortana may currently "only" be an app, rather than an integrated component of the operating system, on Android, but that may soon change -- at least on the coming Cyanogen Android distribution.
Microsoft and Android operating system vendor Cyanogen announced a partnership back in April which called for Cyanogen to distribute some of Microsoft's consumer apps and services with its Open OS platform. At the time, the list of services that Microsoft officials said they'd customize and provide to Cyanogen included Office, Skype, OneDrive, OneNote and "Bing services."
It seems those unspecified Bing services include Cortana, Microsoft's personal digital assistant that is powered by Bing. Cyanogen CEO Kirt McMaster told Internal Business Times this week that Cortana was coming to the Cyanogen Open OS platform.
