If you’ve installed Ubuntu 12.04 LTS (which comes with Unity by default), and got bored with Unity or Gnome Shell – then KDE is probably the best option for you. It’s simple, elegant, easy and comes with the bundle of cool applications. KDE is recommended for beginners (who have migrated from Windows) – because it looks somewhat similar to Windows.
Some of the most popular applications you would get with KDE bundle are – Dolphin File Browser (Lightweight and fast), Konqueror browser, Cool looking Plasma Desktop/Oxygen Themes, Kmail (Default Email Client for KDE desktop), Kate (text editor, like gedit), K3b (best disc burning application) etc.

That’s All, Now you can logout from the current session and select KDE on the Login Prompt to start enjoying the Kool Desktop Environment (KDE).
