Microsoft CEO Steve Ballmer launched the much-awaited Office 365 on Tuesday, after a beta program of about nine months, as the company responds -- some critics say belatedly -- to the rising popularity of cloud-based applications for collaboration and communication.

"Office 365 is where Office meets the cloud," Ballmer said at an event in New York.

Office 365 is the next version of the BPOS (Business Productivity Online Suite) collaboration and communication suite. Among the main improvements in Office 365 is that its applications, including Exchange Online and SharePoint Online, are based on the 2010 version of their on-premise counterparts, while BPOS' are based on the 2007 version. Office 365 also comes with Lync Online, which is an upgrade to Office Communications Online.
