"It breaks down to religious shouting because the
differences (the VM features) become too numerous
to count and wind up as fundamental to the VMer's
zSeries experience."

Or like two queens at a dress ball arguing over who
has the best costume when  both costumes do what
they're supposed to do - cover the naughty bits and
keep you warm (zOS vs zVM) while the youngster (Linux)
is trying to find out what new things they can do,
making the two old queens irrelevant.

(of course, a lot of people don't need all the  VM
features, but that's a side issue).

Some observations:

- VM does not sell as many zSeries as zOS does and the
business people want to maximize profit.
- Windows, zOS and zVM are expensive, proprietary OS
and IBM and others would like to replace them at all
levels with Linux.

So, the real question is how can we leverage Linux on
a zSeries in both LPAR mode and under VM and compete
with other OS and platforms?

What have we discarded in the past 3 years because of
the "slow" zSeries and limited memory that we can
resurrect on a TREX/FICON/ES800 to increase the
zSeries repetoire of competitive applications?"
