Why? The main reason is that Cinnamon, which is the Mint interface I chose to review rather than its close GNOME 2.x-based relative MATE, is designed for power-users who already know how to use a WIMP-style desktop. A Windows XP or 7 user who’s never touched Linux in their life will find Mint Cinnamon far more user-friendly than Metro.
You don’t have to take my word for it. You can download Linux Mint 15, which is now is a release candidate, and try it for yourself. Just keep in mind that thanks to Windows 8’s Secure Boot system lock-in, it’s very difficult to install any other operating system on a Windows 8 PC. The easily way of installing Mint, or anything else, on a Windows 8 is to use your PC’s Unified Extensible Firmware Interface (UEFI) settings to turn Secure Boot off.
