I've read where Wayland still has a few other issues.  I'm sure at some
point, Xorg is going to end and the switch will be the only option. 
When that time comes, likely most all issues will be fixed.  That said,
I've also read where some people really like it.  I think it is
installed here and even used by some things.  I've seen the USE flag on
a lot of packages. 

Given this only affects me once a week, I'll stay where I am at the
moment.  It is nice to know there is another option tho.  One that might
even work better.  ;-)
