Apple's iWork suite, long available for your Mac or iDevice, will soon be available on the web. At WWDC Apple announced new web apps that offer similar features their desktop counterparts, right from the web browser, on any desktop platform.
With iWork for iCloud, you can edit existing documents you've saved to iCloud and even create new Pages, Numbers and Keynote documents. The web apps aren't simple -- you can actually create media-rich presentations from the browser.
Clearly designed as a competitor to Google Docs and Office Web Apps, we still have yet to see if it will make a dent. Developers get access today, while standard users will get it later this year.
