"When activities were introduced into KDE 4, they did not make much sense in isolation. In addition to having virtual desktops, there were activities, which the user could create and configure to have different wallpapers and different widgets. Much of the virtual desktop functionality of KDE 3 was absent and not directly connected to Plasma activities. With the release of KDE 4.5, Plasma has reached a much higher level of maturity, and activities can now be integrated with virtual desktops, dual monitor screens, and with the Dashboard feature."
