"The other big gotcha – and the reason you don't see any screenshots – is that you can't take screenshots in Wayland GNOME sessions just yet."
So, pointing a camera at the screen is out, then?
(Yes, I know...)
As has become regrettably typical for the Fedora project, the first Fedora 21 beta is well behind schedule. According to the current schedule on the Fedora wiki, the final version will arrive about a month late, on 9 December. That is if nothing goes wrong during the beta testing phase that's just started. A month might not …
KDE has a backend for wayland although it's probably got rough edges like GNOME.
Desktop Linux will definitely benefit when wayland breaks through and becomes the default. X can be something that runs on top of it and over time might even be moved out of the core packages when nothing else in there depends on it.
I'm really rather hoping we get a tit for tat war between Mir and Wayland in some respect, sort how it took OS X's aqua-desktop-thingy before Microsoft started adding visual polish (or at least attempts at it) to Windows.
Might have to have a fart about with Wayland see what the fuss is all about, although I'm a deb chap really....

Canonical poisoned their own well by imposing an extremely onerous licence arrangement onto Mir (GPL3 or CPL). Significant contributors like Intel walked away from it. Wayland uses an MIT licence so it's basically a drop-in replacement for X and poses no issue.
So I doubt Mir will succeed in the long term unless Canonical breaks through in the tablet space. At present they're more or less having to develop, contribute and maintain patches by themselves as opposed to Wayland which has far broader support.
I doubt an end user would know nor care if it was Mir or Wayland under the covers. The most likely impact on the user experience are that windows and the desktop as a whole feels more responsive and makes better use of their GPU.
Matt Miller (current Fedora project leader) has a take on 'delays' which I hope people will consider:
Fedora's release schedule is a hybrid of time- and feature-based, which perhaps isn't always best communicated (and it's much easier to look at a date and say 'hey, it's that date and this didn't happen' than to understand all the subtleties behind it).
F21 was never planned to be a six month release cycle from the start, and was pretty much expected to have some bumps, since there's so much change involved.
Aside from that, glad you're enjoying the Beta so far. We hope the Final shouldn't diverge too far from the current schedule (we really don't want it to drag out past December).
