This is what Canonical does, though. They like to be experimental and "break the mold," so to speak, and they're no stranger to incorporating strange and new things (Unity), in some cases before they're ready (Pulse Audio and KDE4). And they'll drop projects/libraries/DE's if they like something else better.
I wouldn't be surprised to see them throw Unity out the window on a whim if they found something they liked better. But curmudgeons like me can still slap XFCE on a LTS release and just stay outside of the storm.
Thanks for reminding me of when they switched to pulse audio. It and not unity was why I left ubuntu. They broke a lot of packages w/ the switch, even 2-3 years later when I tried it again some were still broken. That and they killed my alarm clock.
After 9 weeks of MS Server training then 9 weeks of Redhat training at my college I was like hey, let's check out Linux. So I downloaded Ubuntu and now I can say with 100% certainty, don't use Ubuntu! There is no root (aka Admin) login by default and no GUI ability to run things as root. That means if you want to do something administratory, you have to get out some very long, very annoying text commands. It's unbearable. I gave up after trying to install Java. I have heard from friends that Linux Mint is a lot friendlier but haven't tried it.
sudo for command admin, gksudo for gui admin. USE THEM
