If there's a single common theme that permeates the upcoming Windows 10 release, it would probably be "unification". Continuum unifies the once disparate worlds of "Modern" UI and traditional desktop. The OS itself aims to provide a unified platform to develop "universal" apps that will work across all devices, be it desktop, tablet, or even smartphone. Now, Microsoft will unify the app store experience as well. Actually, "app" store might no longer be appropriate, as the new version of Windows Store will embrace all types of digital content, including music and videos.
