I have used Kubuntu for several years and really enjoy its environment. In Kubuntu, you experience a rich GUI along with all benefits of open source community and specially Ubuntu's. While you enjoy getting around with a wonderful graphical interface, you have all benifits of the linux.

When you are looking to use Linux, but requires GUI like windows, then Kubuntu is perfect.

It has a very comfortable desktop, easy use and application search in its search bar, its graphic environment in general is beautiful and adaptable to any user dedicated to users accustomed to the Windows desktop, when installing Kubuntu for the first time you will feel comfortable because of its ease and its very similar desk.

Kubuntu is designed for PC of somewhat low resources and dedicated to users who want an easy-to-use desktop, you can work on it as in another Linux distribution to be Open Source.
