The folks behind the popular KDE Linux desktop environment pushed out version 4.4 recently, complete with a new interface designed specifically for netbooks. Basically a desktop environment such as KDE or GNOME provides a user interface and a number of applications for Linux users.
The KDE 4.4 Plasma Netbook shell is optimized for mini-laptops with small screens. It has a full-screen application launcher and search utility. You can use widgets to display content from web sites in a newspaper-like layout. And there’s also an emphasis on integration with social networking sites.
KDE 4.4 is a desktop environment rather than a complete Linux distribution. That means you should be able to use it with a number of popular Linux distributions including Ubuntu, Fedora, Mandriva, or PCLinuxOS, although the installation methods will vary by Linux distribution.
