Perhaps GNOME has lost its way trying to be everything to everyone. Perhaps it’s just having a mid-life crisis. TheVarGuy pegs it right. GNOME should stick to what it does best if it is to remain relevant, provide a great GUI for desktop/notebook PCs. There’s no need to derail the users who have come to know and love a simple windowed user-interface. There’s nothing wrong with providing a GUI for other devices but why scuttle something that works? Fork or start a new GUI, GNOME. Don’t kill what works.
“GNOME Shell wants to be an interface for smartphones, tablets and other fancy devices on which Linux currently rarely runs, and that endeavor — despite the best efforts of GNOME designers — makes it less useful as an interface for the PCs on which most people are actually running Linux today. You can’t be everything at once, no matter how much you might like to be — or how much proprietary competitors, like Windows, think they can be as well.”
