Microsoft to launch web versions of Word, Excel, PowerPoint
The Office Web applications will reportedly be stripped down versions of the desktop apps. And it looks like Microsoft will offer at least two tiers of service, with an ad-supported version and a subscription based option for business customers.
The next version of Microsoft Office for the desktop will include the ability to synchronize documents over the web for access on the go. So Microsoft clearly expects customers to continue paying for the offline version of Office. Somehow I suspect the company will also set aside at least a few special features that are only available in the desktop version.
