From my memory GNOME 3 and Unity were created because there was a trend to make all interfaces both desktop and mobile friendly, Ubuntu tried to ship a phone using Unity, and GNOME 3 was advertised for its tablet friendly interface.
For Windows world there was Metro UI of Windows 8, Apple insisted on using different UIs for desktop and mobile and was laughed at.
