An X11 apologist tries Wayland
From https://wiki.ubuntu.com/Wayland
"The X11 protocol was designed around running graphical apps across the network. While some people use this feature, it's far from common. Wayland drops this requirement as a way to greatly simplify its architecture."X client and server are usually the same machine, but they don't have to be.  While on the road, you can use your notebook to open a Gimp session on your home machine and edit an image stored there.  That is, the Gimp runs on your home machine while your notebook has the GUI.This is a lot to give up for cool compositing effects...
