Apple’s Roger Rosner announced iWork for iCloud today at WWDC. Using iCloud users will be able to fully edit Numbers, Pages, and Keynote documents via their web browser regardless of the operating system they’re working on.

Yes, since iWork for iCloud is accessed via a browser you can even edit documents in Windows.

The most impressive feature shown was how powerful the programs editing capabilities were for being available in a web browser.

Users can drag and drop images from their desktop into their documents and have them seamlessly integrate into the document. Text editing includes powerful tools like context sensitive formatting.

In addition, iCloud can now add, convert, and edit Word and Office documents directly from the web interface. For commuters who have to jump from computer to computer while traveling this is going to be a big deal.
