Agreed, but the numbers have been going down for decades, and are still going down. In 1985, mainframes brought in $14bn of IBM's $50bn turnover. Today it's less than $5bn of IBM's $100bn turnover. Factor in inflation and the decline is even more dramatic. IBM used to be able to charge $1 million just to install its top-level mainframe OS (before rental charges) and C cost $1,500 a day. I expect those days have gone ;-)
