Web (Operating System) OS - Glide

Glide

Its product is a "virtual computer," as the company calls it. Hosted at Amazon Web Services, it's designed to be everything you need from a computer, except it's not on your computer. You get a file system (with 5GB of storage for free), a media player, and links to some apps. For example, if you want to edit a word processing file, you can launch it into Thinkfree or Zoho

Glide is more of Web application suite than a Web OS. It's more mature than Ghost, and more comprehensible to the average user today
