No mention of Mir. This is pretty huge news, if long due. It's still baffling to me that they struck off on their own with Mir rather than embracing Wayland, which is now shipping as default in many distros.
I hope one lesson FOSS as a whole takes from this is that duplication of effort can be an incredible waste. The latest Unity8 video shows a UI that, while slick, doesn't look like it delivers a substantially different user experience from GNOME3 + a dock extension.
My mind reels at the number of person-hours that must have gone into re-implementing a dock, notifications, task switching, etc. This was a large corporation, not one homebrewer scratching an itch.
@jplebreton whoa what / yes exactly, can u imagine all those hours of work went into gnome3 and wayland instead
