iWork for iCloud is how Apple will make iWork available on the web, and on devices that don't run iOS or OS X, and now they're making the beta available to even more people. Originally announced at WWDC 2013, Apple first invited developers into the program, but as of today, non-developers are getting invited as well. Here's what Apple's email says:
We’ll soon be introducing a new and exciting feature to iCloud. It’s called iWork for iCloud and it’s a suite of apps — Pages, Numbers, and Keynote — that make it easy for anyone with an iCloud account to create and edit great-looking documents, spreadsheets, and presentations right on the web.
We’d like to invite you to be one of the first to try it, so we’re giving you early access to the iWork for iCloud beta. All you have to do is sign in to iCloud on a Mac or a PC using the current version of Safari, Chrome, or Internet Explorer. Then just click on Pages, Numbers, or Keynote and you’re off.
We’re really proud of these apps and we’d appreciate your help in making them as great as they can possibly be. So we’d love to hear your feedback as you use them.

As advertised, just log in and you're good to go. I've been trying it out since the dev period, and for a web app it's gorgeous. Apple hasn't shown off any Google Docs-style collaboration yet, but all the page-layout stuff and Mac desktop and iPhone, iPod, and iPhone mobile compatibility looks great.
If you get invited to try out the iWork for iCloud beta, let me know what you think!
