This is a UI for Linux that gives users a Metro styled screen to use on their Linux desktop. This looks like the Metro start screen, but you have to build the menu yourself. Metro might come to Linux in a proper fashion, but I am not sure if this would be a good thing. There are no plans to bring the Metro UI to Linux using Mono according to the Gnome developers, this does not exclude the possibility of someone else creating a fully functional Modern UI styled menu for Gnome that could act the same as the Microsoft equivalent. The push to tablet interfaces for desktop computers is a modern thing, the television advertisements all show tablet touch interfaces and users swiping across the screen to navigate the menus. Strange to have this on a desktop machine though. The Windows Server 2012 operating system has the Metro UI as the start screen. Why? Why would you have a touch interface for a server operating system. At least the Red Hat Enterprise 6.4 distribution still uses the Gnome 2.28 desktop. And it has a lovely theme as well. it is more functional than pretty, but for a server operating system that is all you need.
