Nearly two months after the technical preview of the Office 2010 desktop applications, Microsoft has unveiled a technical preview of the Office Web Apps to a select set of testers, among them TechRadar.
You can use Firefox and Safari on Mac and PC as well as IE to run them; Chrome isn't officially supported but it seems to work with the Office Web Apps with no problems.
The web-based apps are brand new, but they just show up as a new menu option in Windows Live SkyDrive.
As well as uploading files you can now create them, and as well as downloading a file you can view or edit it.

You can also search documents – and you get a web-based version of the new navigation bar from Word 2010.
