Microsoft has released a free online version of its Office 2010 productivity suite.
The suite, Office Web Apps, will offer slimmed down versions of Word, Excel, OneNote and Powerpoint for use online, reports The Financial Times.
Microsoft hopes that Office Web Apps can grab some of the market in cloud-based productivity suites currently held by Google Docs, Adobe Buzzword, Zoho Office and others.
Like rival services, Office Web Apps will allow users to view, share and edit documents online.
Office Web Apps will not provide all of the features included in Microsoft's Office 2010 desktop version, lacking such things as the ability to edit video on PowerPoint. Instead, Web Apps will concentrate on more web-friendly features such as the ability to embed tags into documents and post them on blogs.
Office Web Apps is currently available to customers in the United States, the United Kingdom, Ireland and Canada, through company's Windows Live SkyDrive portal.
The full Office 2010 productivity suite is priced at $499 ($349 download) for the Professional edition, $149 ($119) for the Home and Student edition and $279 ($199) for the Home and Business Edition.
