A new user interface from Microsoft that replaces the traditional Microsoft Windows operating system look and feel. The Metro UI consists largely of a “Start Screen” made up of “Live Tiles,” which are dynamic and continually updated links to applications and features.
The Metro design was introduced in the Microsoft Windows 7 Phone OS and is designed to be a predominately touch-based interface that will work across a large variety of devices, including mobile smartphones, tablet computers, laptops and desktop PCs. Metro is also expected to be the default interface in the upcoming Windows 8 release.
