While netbook was the ultimate gadget, a lot of Cloud based OSes were being developed and I had done a review of JoliCloud OS here. The OS has moved quiet ahead since the review and has now hit version 1.0. This version is stable, has build-in touch screen support and a whole new interface which is much more intuitive along with better performance and wider device support.
Some of the other features include use of HTML 5 for application launchers and a greater range of pre-installed applications with include Gmail and Skype. The App Directory is also expanded to over 700 applications.
When is it available? Right now! Just head to jolicloud.com and get the free OS!
