Rob,

I'm an AS/400 bigot, too <g>. But some of these are not quite correct:

> 
> Tell your bosses this.
> Microsoft uses AS/400's to run their line of business applications.  I 
>believe that Apple does, I know they used S/38's.

     Apple certainly does. We've done projects for them. They also use
     other platforms.

> The AS/400 is more of an open system than Unix platforms.

     It's a bit hard to make this case. Many UNIX platforms provide
     all of the source for their operating system. IBM does not.
     Although there are lot's of APIs available on the AS/400, it
     is not as open as UNIX. However, that might actually be one
     of its advantages...

> The AS/400 supports all of the POSIX standards while none of the Unix 
>platforms do.

     The AS/400 does not support all of the Posix standards. For example
     ASCII terminal types. But it has good support for most of the C
     APIs.

> Do these systems  have as many 64bit applications as the AS/400 does?

      Nope. And none of them provide as clean or as easy of an
      upgrade path.

> The support costs of the AS/400 are much smaller than these other systems.

      I'm not sure how you are arriving at this conclusion. Do you
      have any published figures about this? I suspect the costs
      of supporting UNIX varies a great deal depending on the platform.
