People on the Linux Desktop have been talking about getting rid of X for years, literally. Everyone agrees that X was designed in a very different world from today, and with its client/server architecture it's pulling back the Linux Desktop more that anything else. But nothing ever comes out of it.
In the mean time: * MacOSX used a Unix kernel but they didn't use a line of X11 * Android is based on Linux but again, no X.
Ubuntu is the first distro with a clear plan to actually get rid of that crap. And now people are bashing them? What do you think they should do, start discussing with Debian, Fedora and the others about the best think to do? But people have been talking about getting rid of X for years already!
Here is how it works: 1. Get shit done 2. If other people find it useful/interesting, they'll use it and maybe work with you to improve it.
Never try to do 2. before 1. in Open Source, it doesn't work.
