X is certainly overdue for replacement, and I can easily believe that the price it paid for high cross platform portability has exceeded the benefits.
However, relying as much on Linux specific features as the article describes strikes me as a step too far in the other direction. Are the benefits from these kernel specific features really awesome enough to outweigh the benefits of being portable to at least, say, the *BSDs, and maybe Mac OS X and Solaris?
Linux does not have a huge desktop presence. It has, of course, a huge cell phone presence, but Android does not seem likely to adopt a new window system.
