In my company's case, it's not a matter of asking our vendor to work with
IBM.  The vendor already works with IBM, but has chosen to phase out their
mainframe product and create a new one that runs on PC-based servers.  For
various reasons, the hospital decided to open the field and look for a new
Electronic Medical Record (EMR) package across all platforms.  My
understanding is that there is no viable EMR package available on the z/OS
platform.  This made me wonder -- is there no EMR vendor who chose to
develop their product on the z/OS platform?  I expect that successful
vendors carefully chose their platform(s).  If they are not chosing z/OS,
why not?

I think you're asking what percentage of new mainframe customers run z/OS.
IBM doesn't say as far as I know, but it's over half (greater than 50%)
according to what I've read elsewhere. That's in agreement with my
anecdotal experience.

With respect to the application discussion, I generally agree.
Fundamentally IBM is keeping pace or even leading in providing all popular
(and even not-so-popular) application hosting environments on zEnterprise,
and that's important. (Java is an example where IBM was/is ahead of the
curve.) Also, if there's an application that isn't yet on zEnterprise that
you'd like to see on zEnterprise, ask the vendor, and ask the vendor to
work with IBM. IBM has been increasing its application developer support
resources recently, and there's a steady stream of new applications
announced every month, every quarter, every year.
