TechRepublic takes a look at the KDE Plasma desktop environment.

KDE is to Linux what 7 was to Windows

If you ask most devoted fans, Win dows 7 was the best iteration of the desktop operating system. It still held true to the look and feel users had come to rely on but gave just enough modernity to pull it out of the cold, out-of-touch grip of the software Grim Reaper. That's why, when Microsoft put the kibosh on Windows 7, the community at large was up in arms. They didn't want to let go of what was familiar and what worked so well for them. I see KDE as holding the same spot for Linux users. This open-source desktop has been, for some time, the perfect marriage of old and new school design and execution.
