Smallest M/F with z/OS, z/VM, etc. seems to be too big for a lot of small or startup developers. These developers may have great ideas for slick new apps which could be developed on the M/F. The catch is they can't afford the minimum configuration. What's their solution? Probably to develop on a cheaper less robust platform. Later, when they have grown, it's not worth it to make a M/F version. zPDT may help, but there seems to be a large gap between the largest zPDT and the smallest System z; therefore the transition between the two may not be feasible.
Over the years, most management has learned how to find all those hidden costs, so they can calculate reasonable TCO for both M/F and PC farms. In salaries surveys, it is clear that M/F staff get paid better that PC staff. However, we M/Fers need to be careful about saying fewer of us are needed for support. There are companies with a staff 10 or less that successfully manage farms of many many thousands of PC images. I think a lot of customers are over a barrel, because they cannot afford the conversion or the conversion would be too disruptive. Some, not all, vendors take advantage of that. Yes, I'm biased for z/OS because my z/OS expertise is much better that my zLinux skills.
