This isn't the first time you produce strawman arguments like this one.
I don't know why you keep doing it, surely it must be obvious from
reading the list that most people here are not concerned with what the
average consumer needs or wants, or with what is a commercial success in
the consumer arena. What becomes a "commercial success" according to
your definition (sold to millions of average consumers) depends very
little on technical merit and very much on marketing, trends, perceived
coolness, what celebrities do, and so on. There is a huge area of
applications outside of that world where technical merit is actually
important.

I am sure it is very useful /if
you need it./ However, I submit that
the majority of personal computer users do not need it.
Consider: the most popular desktop Unix by an order of magnitude (or
2) is Mac OS X. It's outsold all other commercial Unix variants put
together.
No X.11 and no networkable GUI.
Consider: the most popular Linux by a similar proportion, with many
hundreds of millions of users is Android. Its GUI is based on OpenGL
on the framebuffer, with no networkable GUI.
In fact it is fair to say that/only/ deskop/portable/handheld Unix
variants that*don't* have X.11 have been commercial successes.

Conceded, yes. But Windows shows that
this is possible on a
single-user OS with no multiuser support: it's one user at a time, per
machine. Yes, there are hacks to make it multiuser -- Terminal Server,
Winframe, Citrix, and desktop solutions such as Softxpand or BeTwin.
But as standard, it isn't. No vconsoles, no ssh or telnet, nothing.

Absolutely. But
trying to be all things to all men leads to bloat.
To invoke the Pareto Principle, the way to slim, elegant S/W is to
work out the 20% of the features that are all that 80% of users need.

For me, what is interesting is the direction that the mainstream of
the computer industry is going. It moves like an am?ba: it extends
exploratory pseudopods in multiple directions at once, and when one of
them finds an advantage -- or if you like, when it finds a toe-hold in
some niche -- then the rest of the organism goes that way.
So what is interesting, I think, is to work out which of the many
little niches and crevices and crannies currently being explored is
the one (or one of the primary ones) that will set the new direction.
I personally am not so concerned with the little nooks and crannies
that have been left behind -- except that I like to own and play with
some of the vintage computers that I can now acquire for no money.
Which is why I'm on this list.

It was thus said that the Great Liam Proven once stated:
I personally am not so concerned with the little nooks and crannies
that have been left behind -- except that I like to own and play with
some of the vintage computers that I can now acquire for no money.
Which is why I'm on this list.
But I am. One little nook that seems to have been overlooked by the
mainstream computer industry is Synthesis OS, written back in the early 90s.
It could run Unix software *faster* than Unix, on the same hardware [1],
even though it was the furthest thing from Unix you could imagine. The best
explanation is "Just In Time compilation of the kernel" [2], which is even
more impressive when you consider it was written in assembly.
The thesis describing it [3] is mindblowing, and I keep reminding myself
to write the author to see if I could get a copy of the source code, just to
see how it worked.
But while JITs have become popular for languages (and by extension, user
code), no one seems to have picked it up for operating systems, which is a
shame since it seems the concept is just ripe for solving the C10M problem
[4].

magnitude faster ... )

So yes, you can run X.11 apps on OS X, but OS X's native GUI is not
X-based and not X-compatible.
By comparison, there is ChoX11 for RISC OS, which translates X API
calls to RISC OS API calls and so allows X apps to run natively on the
RISC OS desktop, without an actual X server being involved at all:
http://www.riscos.info/index.php/ChoX11
The point of this comparison being:
* Being able to run X apps doesn't mean being based on X
* Being compatible with X does not mean having an X server
* X can be implemented as a layer on top of other GUIs
* This is comparable to how both Wayland and Mir plan to implement X support

Interesting - thanks.
Yes, I've been impressed myself by how well things like Rdesktop work
these days. I know whole offices full of people on thin clients
running entirely via remote-desktop sessions /over the public
internet./ It is actually entirely viable now.
