Update: It appears that Apple is expanding beta invites to free tier developers, previous reports of public access were likely erroneous as the company has confirmed to The Next Web that non-developers cannot sign in to the suite.
The company sent out emails to registered developers, inviting them to try out the latest version of the Web-based service, though AppleInsider has received unverified reports that non-developers are also allowed to sign in to beta.icloud.com so long as they have an active Apple ID.
Developers have had access to the beta since Apple's Worldwide Developers Conference, where iWork for iCloud was first announced.
As previously outlined in June, iWork for iCloud offers access to Pages, Numbers and Keynote in an experience optimized for Web browsers. The service is compatible with Safari, Chrome or Internet Explorer.
A quick run through of the service shows all of the promised features to be intact, including Microsoft Word document imports.
Apple's iWork for iCloud is still missing some major features that competitors like Google Docs have long provided to users, such as dynamic collaboration tools, but overall the suite is one of the more robust Web productivity suites available.
