Someone whom actually knows how to write up this kinda of thing should do so and put it to the Unity developers to review. Please, please, please, someone do this and soon.
Maybe we could get Unity-Next (8) but without Mir running on good old X11 on Ubuntu 14.04 LTS.
It's a demonstrable fact.
There are significant, show-stopping bugs and other user experience frustrations that they refuse to address. Don't care. It's all phone focus now.
Every release is a beta release, including the LTS. Addressing user concerns is way, WAY down at the bottom of the priority list.
All the "spyware" can be switched off and uninstalled. I've tried 12.04 and I can't stand it, 13.04 is so much better and faster. Switch to it, you won't regret it.
Ubuntu is probably moving with such a fast pace to mir because they DO NOT want to maintain unity7 for the next LTS cycle. The unity8 codebase must be so much cleaner not only because using QT/QML2. 13.10 will feature the beta of mir and 14.04 LTS will incorporate it. Sounds perfectly doable since unity8 and mir at least has sane design.
Does not want.Unity 7 improvements being planned ... in-dash payments.
