SAN FRANCISCO, July 16 (UPI) -- Microsoft says its upcoming Microsoft Office15 productivity suite will work with touch, stylus, mouse or keyboard across new Windows devices including tablets.

The biggest change in Office, unveiled Monday in San Francisco, is how and where users will access files, as Microsoft moves to a subscription model that will allow users' files saved to the cloud by default.

Office files are tied to a Microsoft ID. Once users sign up, they can download the various desktop apps to a certain number of devices, and content -- saved to SkyDrive -- is always available across their tablet, PC and phone, Microsoft said in a release Monday.

Documents are also available offline and will sync whenever a user connects.

Office 15 will be available in three versions, the company said -- Office 365 Home Premium, Office 365 Small Business Premium, and Office 365 Pro plus.

No pricing information has been announced.

A preview is available at office.com/preview until the final version goes on sale, Microsoft said.
