CloudMe is a web based operating system by Xcerion. Accessible both by browser and cellphone, CloudMe has unique features such as rich online collaboration, social networking and easy publishing.
What differentiates CloudMe from webtops is that is contains a XML virtual machine within the browser, which makes the applications on CloudMe execute locally without doing any server round-trips. This also enables CloudMe to continue to work offline.
Xcerion has been building on the CloudMe service since 2001 (formerly known as icloud).
