The pictures are helpful. MATE is a clean, simple desktop that is intuitive easy to use, and easy on resources than the big fancy resource hogs that Gnome and KDE have become. I do hope they can keep the rusty way(land)ward cruft out of Xfce and MATE going forward.
I spent two hours yesterday trying to format a USB stick and "dd" a copy of Devuan Linux for a friend, using the good old familiar commands (gpart destroy and gpart create, add, newfs, etc) without success. Probably a bad USB stick, I guessed, but then it worked flawlessly using the GUI tools from my old MX-Linux install on a different HDD.
I'm convinced that some computers just enjoy confusing and frustrating humans.
