This post discusses OS/2’s built-in virtualization capabilities, highlighting historical context and user experiences with virtualization technology in the past, particularly in relation to IBM's approach. Users express that OS/2 could have been more successful if IBM had better utilized its capabilities, improved the GUI, and embraced newer hardware technologies earlier. The comments also reference the effectiveness of virtualization seen with VM/CMS and IBM's historical contributions to virtualization, like logical partitioning. There is a poignant sense of unfulfilled potential in how OS/2 was developed and marketed when compared to the modern standards of virtualization.
