Hello Linux Geeksters. As you may know, Mark Shuttleworth’s biggest ambition is to reach mobile-desktop convergence, which means that both the desktop and the mobile platform use the same code base, with an intelligent “responsive” interface.

For now, Ubuntu’s convergence concept has been previously demoed by Jono Bacon, Ubuntu’s former Community Manager, via the Weather App and the Karma Machine.
Yet another convergence-ready application is the default Music app of Ubuntu Touch.
A third party user has created the below demo video of Music app running on Ubuntu 15.04 Vivid Vervet. As you can notice for yourself, the app is working just fine on the desktop and the windows are resizing well.
While the convergence is already ready at code-level, this will be achieved when Canonical manages to make Unity 8 and Mir available for the Ubuntu desktop, replacing Unity 7 and Mir.
If things go as Mark Shuttleworth hopes, the first convergence-ready Ubuntu system will be Ubuntu 16.04, scheduled for release in April 2016.
