Several startups and open-source projects have built cloud-based operating systems, also known as WebTops, such as DesktopTwo, EyeOS, G.ho.st, and YouOS. To date these have mostly been of interest to the open-source development community, but the advent of browser-based "thin clients" like CherryPal and of projects like Midori indicates that fully cloud-based computing could make its way to the masses. Google is also said to be at work on a cloud OS, while a Swedish startup called Xcerion has gained attention for its hybrid, an XML-based system called iCloud.
