At today's WWDC keynote event, Apple announced iWork for iCloud, a new version of iWork that is coming for both Mac and iOS later this year. iWork in iCloud brings Apple's iWork software suite to the web.
In addition to working on iOS and Mac, iWork for iCloud also works on Windows computers and in other browsers, like Chrome. In fact, it supports Chrome, Safari, and Internet Explorer, bringing iWork to all user devices.
iWork in the Cloud will compete directly with Google Docs. Google Docs however does not have the same ability to make documents, presentations, and speedsheets look as nice as Apple does with it's iWork suite.
