New Web-based Microsoft Office to work on Linux, iPhone

A Microsoft blog has said that the Web-based version of Office won't be tied to either Windows or Internet Explorer.

In a blog posting on its Channel 10 site a Microsoft blogger noted that, owing to support of Firefox and Safari, the forthcoming Office Web Applications will run on Linux and the iPhone.

The blogger, Microsoft's Sarah Perez, also noted that Microsoft won't be mandating use of Silverlight, its rival to Adobe's Flash.

"Silverlight is not required," Perez said in the Q&A posting. "Using Silverlight will enhance the user experience, resulting in sharper images and improved rendering. Also, the Office Live Workspace has integrated Silverlight technology into the multi-file upload function for a better experience."

Microsoft has said a technical preview of the Web-based Office apps will come later this year. Microsoft hasn't explicitly said there will be a free version, though executives have said the apps will be part of Office Live, which comes in both free and subscription flavours. Perez took that to mean there will be both free and paid-for options.

On the corporate side, Microsoft has said the Office Web Applications will be tied to SharePoint.
