The release of Kubuntu 10.10 includes both the "standard" KDE Plasma Desktop and the special Plasma Netbook desktop. During the boot processing, KDE determines which of these two is more likely to be "correct" for your system, presumably based on screen size and/or resolution, although I don't know the exact parameters. On my HP Pavillion dv2-1010ez, which has a 1280x800 display, it comes up with the standard Plasma desktop, as I described in my previous Ubuntu 10.10 article. On my Samsung N150 Plus, which has a typical netbook 1024x600 display, it comes up with the Plasma Netbook desktop, which looks like this:
The Plasma Netbook desktop contains a "Favorites" area, where you can place frequently used applications and utilities, a "Search" bar for finding and starting other applications and utilities (more on this later), and some pre-configured folders which roughly correspond to the traditional Application menus. The top panel contains the usual icons and indicators, but in the middle rather than at the right end. Rather than try to cram everything from the normal KDE desktop into a presumably small screen, they have split the "Live" information into a second screen called "Page One", which can be selected through the top Panel.
