The whole philosophy behind Linux development is if you don't like the way something works, either change it, if it is open source, or develop something new if it isn't. If Linus hadn't been dissatisfied with the way Minix worked, we wouldn't be where we are now.

I see nothing wrong with Canonical/Ubuntu wanting to develop their own display server, if Wayland development was where Ubuntu expected it to be by this time, we'd all be testing it now, but as it is, it is just a curiosity that some of us play with and discard, as it really isn't ready for everyday usage.

To quote from here

Ubuntu — possibly the most popular distribution of the open source Linux operating system — is striking out on its own. Canonical, the commercial company that oversees Ubuntu, has made a habit of building new Linux components from scratch, moving away from tools built and used by the larger open source community. That’s rubbing many Linux developers and users the wrong way, and now Canonical may have finally alienated these hard-core open sourcers.
I added emphasis to what I think is the most important point in the quote, as developing something new is the way Ubuntu works. Many aren't happy about this, but take Unity for instance, there was a huge amount of hate being shown here on the Forum, when it was first released, but now for the majority of users, it's just another desktop environment they can use or not, if and when the choose.

I guess what I'm really trying to say, if you want a traditional style distribution, use it, if you want something that may be on the cutting edge, stick with Ubuntu. The LTS version will be supported until 2017, and with the updates in the point releases it will be usable until then on even the newest hardware.
