The telling point, however, is that nothing beats the cost
and small footprint of running z/OS on a ThinkPad. For the
very small ISVs, the one or two person shop that develops
software or, in our case, courseware, is pretty much shut
out then.
But consider the effect on IBM's tech support. Small ISV
laboratories or courseware laboratories are are likely to
generate a PMR traffic disproportionate to the computing
power they employ. Student raises hand. "What if ... ?"
"Interesting question; I'll try it overnight." "Appeared
to be a bug; I submitted an ETR." How would it affect you
if IBM chose to offset this by burdening their charges with
a term proportional to the 0.5 power of processor speed
(enforcing Grosch's Law)?
Not the way it works. If I do a test and find it works
differently than expected, I don't report a defect but
simply tell the student how it works in the real world.
I have reported the occasional bug and the more frequent
doc error, but I tend to do it informally through contacts
instead of through the formal procedures.
OTOH, IBM might benefit from ISV's actually paying IBM for
the privilege or performing field tests (Linus's Law).
The gripping hand is that IBM likely sees little business
motive, except in terms of reputation, for repairing defects
that don't affect its larger revenue customers.
