2% after 30 years in the making, and hatred for the GNOME and KDE communities, always pushing for PDP-11 experience with multiple xterms like I was doing in 1994 on IBM X Window terminals on the university campus with DG/UX, I already gave up around Windows 7 release.
Fact is the people who developed X thought through multi user graphical computing.
That process has not really happened since.
It needs to, or we just won't see desktop Linux compete.
