Yeah IBM really created a false dichotomy.  Production users want the mainframe architecture and reliability.  Developers are fine with emulation and create demand.<p>I&#x27;ve got to imagine they are barely breaking even on a minimal config baby class system.  The yield on an MCM has to be minimal.  You can find videos of how labor intensive the build of a frame is, let alone the engineering.  I wouldn&#x27;t even be surprised if they were loss leaders.<p>And that begs the question, why not grow the user base with aggressive placement, training, and development.  Another $1 billion investment in Linux has no appreciable affect to most mainframe users, and no way there is an ROI.  Imagine that injection on this small, loyal platform of users.
