The new version of Office, Microsoft's productivity suite that has been synonymous with computing life since the '90s, entered public preview today and is ready for a test drive at Microsoft's official website.

Office 2013 differs from previous versions in a few key ways. First, since it's optimized for Windows 8, all included programs, including Word, Excel, PowerPoint, Outlook and One Note, are completely touch capable. Second, Microsoft is offering a new subscription service called Office 365, which gives the user, among other things, access to the full suite of programs, as well as recent files, from any computer via the cloud.

And of course, each program has received design and usability improvements, including the ability to edit and create PDF files in Word (FINALLY). Check out a video tour of the new software above from our friends at The Verge.
