Apple Launches iWork For iCloud To Everyone
Anyone with an iCloud account can now use Apple’s iWork suite via the Web. Beta versions of Pages, Numbers, and Keynote are now available at iCloud.com.
First introduced at the Worldwide Developers Conference in June, iWork for iCloud is accessible from both PC and Mac computers, as well as mobile devices. Thanks to iCloud, any document changes made on the Web are automatically pushed to Mac and iOS versions of the suite, and vice versa.
I have used this on a PC as well as on my iPad, and it works really well.
