Microsoft has finally launched its long anticipated Office 2013 product. Today the OS and productivity app giant officially launched its Office 2013 and Office 365 products to the consumer market.

In its ever present, yet slow march towards having everything in the "cloud", Microsoft has built a new subscription model around the latest Office products. Starting today consumers will be able to purchase a subscription to Office 2013 through its new Office 365 service.

For $99 a year, subscribers will get access for up to five office installs on Mac or PC's which includes access to Word, Excel, PowerPoint, OneNote, Outlook, Publisher and Access. As an incentive Microsoft is also bundling 20GB of additional SkyDrive space and 60 minutes of Skype calling per month with each subscription. A monthly plan of $9.99 is also available.

Non-subscription packages of Office Home and Student and Office Professional are also available for $139.99 and $399.99 respectively. Finally, Microsoft has ditched using physical media to get Office onto consumers PC and is relying on users downloading the software from the cloud. Even "retail box" versions will only include download instructions.
