JoliCloud, an optimized Linux based OS aimed directly at netbooks has just entered public pre-beta. This change comes bundled as two updates. Immediate differences include a new welcome screen and, most notably, the newly added ability to be installed directly from your Windows 7 or Windows XP machine. Additionally there will be added support for the GMA 500 chipsets. With these new additions 98% of all netbooks on the market are currently supported. There are currently plans to support the NVIDIA ION chip set however so far that update has yet to be released.
