Durable, through HUGE maintenance contracts. Though...
I should have said:
Besides IO, the only real thing mainframes do better than many
other systems, that I know of, is COST a lot of money to
maintain and upgrade.
Some costs I have seen in the past, associated with "mainframes":
* $50K just to get TCP/IP enabled on a single network interface.
* $120K to enable another, already there, processor.
* $60K to "update" the disk IO scheduler, that was mistakenly
ordered with the wrong configuration
I could mention others, I don't have all day. These were all done in
about 30 minutes after a P.O. was cut and faxed.
