Google's Chrome OS has been the darling of open source developers for a while, and now it just got a bit more serious.
ChromeiumOS64 is a new Chrome project with 64-bit support and it should
offer a bit more potential for more serious use on proper, 64-bit CPUs.
In addition to 64-bit support, ChromeiumOS64 also features Xen
hypervisor! and allows users to run virtual machines on Linux or even
Windows.
Sounds neat and it's just 1GB to download, although developers claim it
requires 16GB of room to breathe. If we weren't so busy, and at the
same time so lazy, we would try it out ourselves.
