JoliCloud has been a long time coming, but you can finally download it today. It's a touchscreen-compatible, Linux-based operating system that promises that simplifies your netbook experience. It looks neat, boasts a 700-app directory—and it's totally free.
I agree with designer Tariq Krim that we've yet to see an OS interface perfectly implemented to a netbook's uniquely small hardware. Hence Jolicloud, and judging from this UI shot, he's on to something.
