Apple has made iWork Beta available to all users with an iCloud account.
If you go to iCloud.com it will prompt you for your Apple ID, once you enter that you're in. You will have access to the iWork applications (Pages, Numbers, and Keynote) as well as the Find My iPhone function, notes, reminders and mail. You will have to setup and iCloud email address to use the mail function. You can work on documents and save them here, and there is also an option to download the file.
Test it out, Apple originally only had this available to developers, but it's pretty handy.
