Considering the fact that they thought that giving an incoming 
email the power to read your address book and send emails to 
people on it was a fine idea, it's a shock that they have figured 
out how to alternate inhaling and exhaling.

Both concepts "real time" and "embedded" are really understood in many ways.
You can find numerous definitions for both, easily.
All OS'es can be used in embedded systems of some kind. Some just perform
better doing this than others....

Are you referring to QNX with that?

The Spellchecker Song:

I have a spelling checker. 
It came with my Pea Sea. 
It plane lee marks four my revue 
Miss steaks aye can knot see.

Eye ran this poem threw it. 
Your sure real glad two no. 
Its very polished in its weigh, 
My checker tolled me sew.

A checker is a blessing. 
It freeze yew lodes of thyme. 
It helps me right awl stiles two reed, 
And aides me when aye rime.

Each frays comes posed up on my screen 
Eye trussed too bee a joule. 
The checker pours o'er every word 
To cheque sum spelling rule.

Bee fore a veiling checkers 
Hour spelling mite decline, 
And if we're laks oar have a laps, 
We wood bee maid too wine.

Butt now bee cause my spelling 
Is checked with such grate flare, 
There are know faults with in my cite, 
Of nun eye am a wear.

Now spelling does not phase me, 
It does knot bring a tier. 
My pay purrs awl due glad den 
With wrapped words fare as hear.

To rite with care is quite a feet 
Of witch won should be proud, 
And wee mussed dew the best wee can, 
Sew flaws are knot aloud.

Sow ewe can sea why aye dew prays 
Such soft wear four pea seas, 
And why eye brake in two averse 
Buy righting want too please.

And the unteachable annoyance fails to snip 70 odd lines of
irrelevant quotation, while irritating the world with YATP.  PLONK

Soon he will be plonked by everyone here and we can go back to
discussing embedded systems without a yapping (yatping?) little 
dog bothering us.

BTW, there is no need to call me "God."  "Guy" will suffice. :)

Getting back to the subject of QNX, it has been a while since I 
used it on a project. I usually work on the low end (4-bit uP with
64 nybbles of RAM) but the next time I find myself needing a high
end RTOS for PC hardware, I will be looking at Embedded Linux and
at QNX.  My experience with QNX was very positive.

"Self appointed GOD" was the phrase used, stooping to misquotes? You'd 
make a good politician, blinkered perspective and all, perhaps you'd 
have more success there than your sig seems to indicate you're having at 
embedded systems? Just trying to be helpful.

? That wasn't a quote.

Tell us - what is your expertise in embedded systems? You haven't seen
fit to share any of it yet, which would be appropriate before
maligning others.

But I forgot, you're handicapped. I just realized what  it is - one
stone. While I'm sympathetic for your loss, that really shouldn't
affect your performance much.
