I don't think that the writer of the document (Dr. Rubin) compares apples to apples. IBM mainframe does not operate the network (DNS, DHCP, AD, email servers and many other base services). there are some tens of servers that has no comparable service in the mainframe world. The mainframe, from this point of view, is just another server, and the comparison should compare mainframe applications vs alternatives (re-hosting, rewrite), or the other hand - moving a server application into the mainframe. There are many questions to be asked about IBM marketing strategy, most has been asked in this thread. Have you even thought why does Cobol program runs much faster on wintel then a mainframe? Why is sorting much efficient on wintel? I am sure most CEOs knows what their spending is, and where the budgert goes. And at end, if they could begin from scratch, i am sure most of them wouldn't select mainframe as their platform of computing. would you?
