Exactly how often do you think people want to run 1000 nodes on
a single problem? When was the last time you did that?

Realistically, the majority of parallel jobs are in range 4-128 
processors, depending on what you want to do and how the code scales. 
SGI's do fine in that space. So do other non-beowulf systems or
no one with sense would buy them.
