I disagree with your assessment. Mir might not have anything to do with
Unity now, but in the future the stated goal is to get Unity running
directly on Mir, allowing Canonical to throw out the X11 layer
completely and move to supporting X11 in a secondary way, like OS X
does. Unity and Mir will then become the platform, much like OS X's
platform is defined by Quartz and Cocoa. I expect Ubuntu apps to be
Mir-native, and to have tight tie-ins with the Unity desktop. Unity
will be Mir's interface to the world. Hence they will in fact become
related rather closely, unless Canonical decides to switch to Wayland,
which is very possible given little support from Nvidia, ATI, or Intel
I don't say all this to bash Ubuntu or even call it a bad thing. I'm
just pointing out things as I see them.

You are correct about Unity's origins, but you can no longer say Unity
has anything to do with Gnome 3. In fact Unity is moving development to
Qt. Unity 2D, which made a brief appearance a couple of years ago was

Yes I understand that very well. But if Ubuntu is the only distribution
using Mir, and if Unity only runs on Mir, then at that point the
difference you mention become moot. Unity on Ubuntu no longer will be
just another desktop option. It will simply be *the* Ubuntu desktop,
like Quartz/Finder/Dock is on OS X.
The end result is that someone will only target Mir in their application
if they want to run on Ubuntu, and if they want to have a nice,
integrated app on Ubuntu, they will tie into and use Unity. At that
point, for better or worse, Ubuntu becomes its own complete platform,
like Android, or OS X. At present I don't have any feelings one way or
the other about this. As long as good toolkits exist that abstract the
backends, then supporting Ubuntu is no more difficult than adding a
build target in Qt. But this is the point at which Ubuntu starts to
diverge from "Linux." That's all I was trying to say.

I think this comparison is not accurate because all of these things you
mention can more or less coexist and be swapped back and forth
interchangeably. When Ubuntu completes the transition to Mir, Ubuntu
software and the Unity desktop will, in its binary form, be Ubuntu-only.
Unity will be Ubuntu-only, since it's doubtful other distros will
support or ship Mir. Software written for Ubuntu will be Ubuntu-only as
most other distros will be running Wayland. So I guess
I stand by my opinion that Ubuntu is diverging from the rest of the
Linux world and is heading off in its own direction. Maybe my tone
implied otherwise, but I'm not stating whether this is a good or bad
thing--I simply don't know.
