Apple wants Windows and Android customers to use its iWork productivity suite as well so they announced that now everyone can use Pages, Numbers and Keynote web applications through the iCloud Beta web interface, even if they don't own Apple devices.
An Apple ID account is still required to access Pages, Numbers and Keynote for iCloud, but the big news is that people can now create an Apple ID on the fly.
As noted by MacRumors, the announcement was made yesterday on the beta.iCloud.com website, indicating that these web apps may soon be accessible through the regular iCloud.com website, too.
