Chromium has made huge leaps forward. You can load web pages, follow links, and work (somewhat) with tabs. There's no support for plug-ins, and the browser remains fairly unstable, leaving as it did a wake of hung processes which I could follow using Leopard's Activity Monitor. As this second video shows, many features remain unimplemented, and basic features (like closing windows) may fail.
