“Blogger Lee Mathews of Download Squad recently found a reference to Chrome OS in the source code of Chromium, the open source project that serves as the testing grounds for Google's Chrome web browser. In the code, a line references something being called the "Chrome OS login manager." Essentially, this login manager will function as a single sign-on (SSO) cookie which will simultaneously log you into all Google services including things like Gmail, Calendar, Docs, Reader, etc.” - × × ×
