The Metro user interface is without doubt the
most controversial feature of Microsoft's upcoming operating system
Windows 8. When you dive deeper into the criticism that Metro faces, you notice that one argument stands out among the majority of critics: Metro is for tablets and touch-devices and not the desktop.
While it is possible to use Metro with a mouse and keyboard, its big buttons and controls, like the Charms menu and swiping motions, do cater to an audience that uses touch-devices. When you look closer, you will also notice that Metro does not really offer anything that desktop users can't do on the PC or on the Internet as well, oftentimes even better.
