Officially joining the browser-based productivity game, Microsoft late Monday released the browser-based versions of Word, Excel, PowerPoint, and OneNote.

The Office Web Apps, as the programs are dubbed, are slimmed down versions of the desktop counterparts, allowing for document viewing, sharing, and lightweight editing. Consumers get free access to the tools, along with 25GB of storage as part of Windows Live, while businesses can also host their own version of the Web Apps using the latest version of Sharepoint. The main catch is that using the browser-based versions require an active Internet connection.

"We'll have more to share next week when Office 2010 is released to consumers, including how Office 2010+SkyDrive+Office Web Apps give you the best productivity experience across the PC, phone, and browser," Microsoft's Jason Moore said in a blog post. "In the meantime, if you live in the US, UK, Canada, or Ireland, you can head over to Office.live.com today to start viewing and editing Word, PowerPoint, Excel, and OneNote documents right in your web browser-and share them with your friends."
