By now volumes have been written about why Canonical will replace its own Unity desktop with GNOME so I won’t bother to express any further opinion on the matter. The only thing I will say is well done GNOME!
I use KDE, but GNOME is awesome too. No doubt Canonical will hack the shit out of it, but nonetheless a real open source project will get a hell of amount of publicity from the move.
Forking Linux distributions is hard, developing display servers is hard and developing desktop environments is even harder so often it’s just best to use what’s already being actively developed.
To that end, enjoy some exciting developments in Plasma land…
