"Is there any reason this phantom Fortune 1000 Company could not be HP??"
No, but IMO I doubt that it is HP. HP is in the 2009 Fortune Top 10 Companies, let alone technology companies, so to me the question would be if it is HP, why use the words "Fortune 1000"? Why not "Fortune 100" if you wanted to draw someones attention? JMO.
Good luck everyone.
