Chrome OS. Man, seems like Google has gotten its hands into quite a few things since we last heard of that, but the underground is keeping things lively with new builds of Chromium OS -- you know, to keep us satisfied while we wait for the real deal. Hexxeh has just unleashed its latest build, dubbed Flow, which makes a few critical improvements, particularly if you're planning to install the system onto an Ion-based rig. Flow includes full NVIDIA Ion acceleration, and it also "improves battery life" while making the automatic update... um, work. Hit that source link to get your download on, and if you've been holding out for fear of trying something new, you've got your whole weekend to fix things should things go terribly awry.
