I would like to see those TCO studies. Truth is there are a lot of companies (big ones included) that are moving off mainframes to reduce the TCO. Those "distributed" systems come in "very" big iron configurations and are
starting to match mainframes for RAS. Sad but true.

The truth is there are no honest TCO studies. You pay for what is proven the study.

The other truth is mainframe is *considered* as expensive and obsolete. Of course people who knows mainframe are *considered* as biased.

The truth is that sometimes good enough is OK, so people do not want to pay for RAS capabilities.

Last, but definitely not least is the number of new mainframe customers and customers at all very big secret - why ? ;-)
We all feel/know/observe the number of mainframe sites is shrinking.
We also know that the answer "but the number of MIPS is growing" is smokescreen - number of MIPS on my desktop grew up significantly, but the number of PCs remained the same.
