This document discusses desktops versus virtual machines and how Colama RDE addresses both. It summarizes that Colama RDE machines are powerful and personal like desktops, yet also upgradable, immune, and centrally managed like virtual machines. It achieves this through features like desktop provisioning from a centralized OS image, creating differential layers for personal changes, taking snapshots to make modifications the new default image, and booting from this image.
