The latest release earlier this month of the K Desktop Environment, or KDE, is a solid upgrade that could very well win back the hearts and fingers of Linux users who wandered off to other, less powerful desktop shells. I am particularly impressed with its smooth integration into the dedicated KDE distribution in Linux Mint 13. I lost interest in KDE after it left version 2.x behind. It was becoming clunkier to use and too much of a hassle to handle. With Gnome 3.x and Ubuntu's Unity environments even less appealing, I bounced between the Cinnamon and XFCE desktop alternatives.
