I've written a fairly lengthy review of Linux Mint 15 Olivia 64-bit edition with the MATE desktop environment, covering live session, installation and post-install use, including basic and extended functionality, networking, look & feel, customization, package management and updates, applications, system resources, stability, suspend & resume, and some problems like a one-time freeze of the desktop in the live session, missing packages in the official repos, wrong permissions on hidden settings folders in the home directory, small visual glitches, and more.
