But you are wrong.  Almost all computer vendors have X.400 software.
However, many of them have chosen to implement X.400 as a gateway
and preserve their existing user interfaces.

Without conducting an actual survey I would guess there are more
commercial implementations of X.400 than SMTP - unless you count Unix
where it is given away for free.

My estimate of investment in X.400 products is somewhere in the $2-300M
range, but I may only know part of the story.

Now, if you ask what sells, my answer is going to be different.  You
will find that the proprietary mail systems such as cc:Mail and 
Microsoft Mail sell the most copies right now.

Cheers,                 ....Erik.
