Linux's live demos, desktop environments, and update rollbacks beat Windows

A Windows user who recently switched to Linux describes three features he never had on Windows: live demos of operating systems, officially supported desktop environments, and automatic backup of previous system versions after updates. Linux distros can be booted from a USB stick to try them without installation, unlike Windows which offers only a 10-day revert period after upgrading. Desktop environments are complete suites that change the entire look and feel of the system, far beyond Windows themes, and can be switched at the login screen. Fedora retains the previous kernel for two updates after each system upgrade, allowing users to boot into an older version if an update breaks something. This is a simpler failsafe than Windows' manual update uninstallation process.
