On desktop my preferred environments are Xfce and i3, but I wonder why GNOME isn't pushing in this same direction as Plasma Mobile and Unity. (Unless they are and I'm not aware?) It seems like out of all the main DEs, GNOME3 is the nearest to being suited for mobile and touch screens, perhaps more so than Unity (IMO). A google search turns up a few initiatives/blog posts throughout the years that speak of bringing GNOME to mobile, but nothing seems to have come of any of them as far as I can tell.
