The Web is quickly becoming the new platform of choice for many tech companies. Google and Microsoft have been the two largest proponents of the Web over the last few years with both companies investing heavily in cloud computing and big data. Now Microsoft has finally updated one of its first forays into the Web-based collaboration software.

Microsoft announced today that all of its Office Web apps have been updated to take advantage of new platforms like SkyDrive. The first Office Web apps were made available in 2010 and let users collaborate on documents in real time via any Web browser. It was similar to Google Docs, but now Microsoft is moving to be the Web platform of choice for those working in Word and other office documents.

First up, the Word Web app was updated to improve its visuals on high definition monitors. There’s also new support for viewing and adding comments to a Word document. Many of the same features present in the desktop version of Word are available in the Word Web app.

The Excel Web app features all of the essential features that you’ve come to expect. Users can now visualize data with high fidelity charts, even in 3D. The app now supports the ability to print from the browser as well.

The PowerPoint Web app has received more updates than most due to its highly visual nature. Slides are now presented in high definition, just like on the desktop version. Audio and video playback is now supported on mobile devices as well. Students or office workers who are still working on a presentation at the last minute can also add new slides via a Web browser.

On a final note, the OneNote Web app also received a few updates including the ability to search on a page or within a section. Like before, users can type anywhere on a page to add notes, pictures or tags. Those notes, however, can now be shared as URL that can be viewed on across PCs, phones and tablets.

All the new updated Office Web apps have been optimized for IE10, Windows 8 and iOS 6. You can access them via SkyDrive and Outlook.
