What was interesting to me was the listing of IBM as a partner. "Forming relationships with major partners: Intel, AMD, HP, and IBM." So Intel/AMD make x86 Chips. Intel/HP basically do Itanium. What's IBM doing on the list? Sure they build X86 servers, but so does Dell etc. Is there a potential to see Windows one day running on Power7? (Other option I guess is something to do with the XBOX3 - but that also doesn't seem to fit) Any ideas?
