During its big unveiling of the new Windows 10 operating system, Microsoft demonstrated a feature called Continuum, which is designed to make it easy for users to switch between touch interfaces and non-touch environments.  With Continuum, Microsoft says the new interface design smoothes those transitions. Microsoft says this interface was built specifically for devices such as the Surface Pro 3 and Lenovo Yoga, which have users switching between touch and non-touch interfaces often. Users will be prompted to switch between the touch and non-touch modes whenever they connect or disconnect the keyboard, and the Start screen and apps will adjust themselves accordingly.
