As Computerworld's Steven J. Vaughan-Nichols explains, Canonical has always offered commercial support for Linux, though its services largely targeted the enterprise market. Today, Canonical is announcing its plan to extend commercial support services to Ubuntu desktop users: individuals and small- and mid-sized businesses desiring a dedicated helping hand with Ubuntu installation, data migration, and network configuration.

Canonical offers three levels of support -- starter, advanced, and professional (the comparison chart breaks down coverage nicely) -- for one- or three- year periods.

Typical Linux desktop options like KDE and GNOME  limit the way computer users interact with the applications and programs on their systems. There's not much to do beyond opening and closing an app, and moving or resizing a window. The development team behind Étoilé is building a desktop interface that aims to stand that idea on its head and let users create workflows that work best for them.

The GNUstep-based environment is built with lightweight and modular components that allow users to combine project- and document-oriented activities (or, services, as the Étoilé team calls them) more easily.

Fresh out of the Mozilla Labs oven this week is a beta version of Prism, a new incarnation of WebRunner that integrates Web applications with the desktop. The idea behind Prism starts with from the premise that as more people move their computing activities to the cloud, users will become increasingly dependent on Web apps designed to replace locally-based email, calendaring, and word processing.
