People mostly seem to like KDE Plasma more than GNOME, but Ubuntu still seems way more popular. Will Kubuntu ever overtake Ubuntu? Will people ever default to saying Kubuntu instead of saying Ubuntu even when speaking generally about *buntus?
Same questions for other distros like Fedora/Fedora KDE
Yes, but later it became the standard DE. The original Unity was a great DE for Netbooks.
Indeed it was. I still miss the last Gnome 2 version with 2.32 though (I think).
