That's fine for things unix does well. Realtime is one counterexample.

Big expensive systems. Non-desktop systems. Non-end-user systems. And
clustering will eat its lunch eventually anyway.

NetBSD claims 24 platforms. Forths run on everything you've never heard of
below a PDA.

Again, throughput is a server thing.

And assembler. This is called get your hands greasy. Fun. Your box. Not
the admin's box.

We disagree, but I wont rant about the phone company breaking a perfectly
good telegraphy protocol called ASCII.

Dennis Ritchie, who signs the checks for the people that wrote Plan 9,
said an interesting thing about portability. He said "good code is
portable code." I infer from that, and from the Plan 9 sources, and from
the design of unix and the two-character commands in /bin/, that he
relates good very strongly with simple. Not slavish adherance to
standards. Plan 9 C isn't ANSI, for example. The unix portability suite is
called "ape".

I haven't started X in about a year. I read pdf's as jpegs, I have Xaos
running in SVGA, and so on. Not-unix != Dos . I don't dislike X
particularly, but I live in what I ship, and for maintenance I can't keep
up with console, considering that I'm doing a bit more than just bundling
things up.

Which distro appears simple to the user?

Thanks for replying civilly to something you clearly don't agree with.
Basically, your reply says to me that kernel hackers can't imagine unix as
an end-user OS. Your points are all "that will suck as a server". Of
course. A solid true multi-user open source operating system is a solid
base for a variety of things.
