RE[7]: How accurate can this be?

I can pick third variable in this not-so-simple equation - cost. If you were to buy hardware (with or without software) you have to be perfectly aware what's going to run on top of it. If you are not sure, just buy a Dell appliance, for example, R710, and install whatever you wish on it - Red Hat, Novell suite, MS or even Solaris. That's a good deal in terms of price. Sun and IBM have nothing to offer against it, again price-wise.

There's always a market for reliability like that. It may not be large, but until x86 systems start offering similar facilities the mainframe won't be going away.
I doubt x86 will offer similar reliability, as x86 is too buggy and bloated. To get reliability, you need Mainframes / SPARC / POWER / Itanium. For instance, some SPARC cpus can rollback and replay instructions if something went wrong, just like Mainframes. Such functionality does not help performance, and it cost a fortune to implement.
Reliability (Mainframes) and performance (x86) are contradictory, pick one of them.
