Sorry. My quote induced you to think my question regarded the "general
purpose" statement but it was about "the world's most advanced operating
system" statement.

They are AFAICT closer to general system than other RTOSes (VxWorks,
Integrity etc.) in the sense one can use them as development hosts and
even run some desktop like applications on them (Lynx has a compatibilty
layer for linux applications - I wonder how well it works.) For
applications that involve graphics display of information and data
recovery on a networked system (bedside monitors from which one could
retrieve patients data for instance) they seem to provide an easier path
to final product than some other RTOSes (again VxWors, Integrity etc.)
that need third party componentes to perform the same tasks. I wonder
how good are their development tools though.

Sorry, sometimes my newsreader (Mozilla) does that and I have no clue
why. It happens sporadically and it also mungs my text as well at times.
Had tried Netscape before but the problems were much worse. Also, I
tried both on very different PCs. Same thing.
BTW, I have it set to 65 characters in the setup menu.

Your use of the phrase "some designs" leads me to believe that
you are looking for an embedded OS and possibly a RTOS. If
you were talking about a general purpose OS I would expect to
see you talking about office suites and support for the latest
games on the latest videocards.
Look at http://www.qnx.com/. They aren;t pushing it as something to
replace Windows XP or Linux on the desktop, but rather as something
to put inside routers and DVD platers.
Now look at http://www.lynuxworks.com/. They are pushing it for
avionics, not general purpose use.
If you don't need real-time and your application is to run on a
standard desktop PC used by a typical user - general purpose
computing - Linux is a better choice IMO.
For real-time embedded applications, QNX and LynxOS are both fine
choices.

What's your base for such a statement? I am starting to evaluate it for
some designs. What about LynxOS (my other candidate) ?

I don't know what you are doing to mung quotations from me, but
anything I wrote was limited to 65 char lines. You are converting
them into something that far exceeds standards.

Not a bad methodology, unless you have a competitor who is using
Forth on a uC -- if that ever happens you won't be able to beat
the competition in the areas of time-to-market, system cost, or
development cost. Then again, you might have a competitor who is
using Windowws CE, in which case he is the one who won't be able
to beat yiu in the areas of time-to-market, system cost, or
development cost.

I was a little quick on the post. I see that their PR was limited
to the RTOS domain. QNX (not Neutrino) used to be POSIX+microkernel+
almost real time. It tried very hard to be POSIX and to support boatloads
of hardware, most of which it did OK. Linux has always done much better,
minus the real-time component.

Our designs prefer logic machines to accomplish the hard-time stuff,
and non-real-time OS to support the higher level functions,
and to keep the hardware fed. And of course, where logic is insufficient,
we program sans OS, as God intended.
