but you're stretching definitions to fit your own opinions.
"over 500 Sun boxes" does not equal a "midrange"; they're 500 INDIVIDUAL machines networked together to equal or beat a "midrange's" overall capabilities. And "1400 NT (2003, 2000, NT) boxes with and unknown amount of storage" are nothing more than just that - INDIVIDUAL units networked together. Cumulatively, their computing capacity easily tops one individual "midrange" computer, but that's understood.
So when you call up IBM and say, "Please send me a midrange computer" do you expect 200 units delivered to your door, or do you expect just ONE computer to be delivered?
