I may be wrong as well, but I see the "new" installations, like Google and
many of the other in the top500.org list using clusters of Intel compatible
processors in small (2-4) SMP configurations. I see the market for
mainframes for the people who started on them, and find it easier to
put their legacy apps on newer compatible hardware when parts for the
old systems become scarce, than to rewrite the systems they've been
running their business on for the last few decades. When, as you pointed
out, the apps get ported to Java or whatever, then clusters of cheap
computers will look more attractive for the same reason that RAID took
over from large hard drives.
What "new from scratch" commercial apps are being developed for
mainframes? Even Oracle is looking to migrate customers from their
big iron to RAC. Resisting change is futile.
