Interesting that they decided to "reimplement" stuff again. Nice to see them going with Qt though.
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.
