In the same spirit of Google's new name (see http://www.google.com/ and http://googleblog.blogspot.com/2010/04/different-kind-of-company-name.html) IBM should rename system z to system y, and get rid of the whole zee vs. zed pronunciation debate!
Then sales persons who are also Abbot and Costello fans can use this sales presentation method: Customer: What's the right system for me? IBM: Y! Customer: No, I mean which system would be best? IBM: Y! Customer: Because I want the best! Do you have a system that meets my needs? IBM: Y! You know the rest.. OK, it isn't quite Friday but it is the afternoon of April 1... :-) -- Bruce Hayden - Chuckie made me do it!
