KDE and GNOME, the open-source software projects that together form the face of most Linux installations, have undergone revisions that boost their usability and enterprise readiness—advances that build the case for Linux as a viable alternative to Windows on mainstream corporate desktops.
Some of the biggest changes in KDE 3.3 and GNOME 2.8 lie in the projects’ respective e-mail and collaboration clients, Kontact and Evolution. Both applications are well-integrated into their desktop environments and cover a full range of groupware functionality, but eWEEK Labs found Evolution to be more refined and pleasant to use.
