>Take this (slightly contrived) example: In Gnome 3 you can "zoom" out to panarama view all your running applications, while you have a HTML5 video running in your browser and everything just runs flawlessly, with almost no system-load, and no tearing or any nonsense.
Same with a good compositing X11 window manager. In fact wayland does not dictate gpu accelerated rendering nor compositing. And there is much more to look at when talking about wayland vs X11, many details and a few major things.
But in general, no, wayland is still not ready. The people leading the desktop wayland parade have to all take a step back and think, while nvidia needs to agree with kernel people on how to manage memory. Then we can start thinking about replacing X (start, as there are still many more details).
