Since the introduction of Plasma widgets in KDE4, the whole desktop took a new direction, starting to become a more interactive way to communicate with the user, to say nothing about the fact that a desktop with widgets will look more beautiful than a plain, icon-only desktop.
Below is an overview of 10 plasmoids for KDE with screenshots, which either come by default in KDE or can be downloaded online. To get and install new plasmoids from the Internet, make sure your widgets are unlocked, then right-click on the desktop, select Add Widgets… and then click the Get new widgets button.
Yahoo! Weather Widget

This plasmoid is composed of several modules which can be shown or hidden. There is hardware information, temperature, network, hard disk and memory monitoring. Each of them can be configured.
The nice thing about Now Playing is that it doesn’t only support players like Amarok or Clementine, but also Audacious. Now Playing also has buttons to stop or play the next song.
RSSNOW is a feed reader plasmoid which allows you to add as many feeds as you want, view next and previous feeds, configure the auto-switch feed interval, updates fetching interval, enable or disable animations.
Simple System Monitor
This widget will display information such as date and time, uptime, CPU temperature, OS, kernel version, available memory. You can choose from three different backgrounds (default, crystal and translucent), change the background logo, the critical and high temperature threshold, display temperature in Fahrenheit or Celsius.
This is a simple plasmoid embedding an English dictionary.
This is a a tiny desktop calculator with only the basic features. Very useful for quick calculations, but lacks modes such as scientific.
