Microsoft’s new Office blends cloud services with Office 2013, the core desktop application.  As sleek, revamped appearance and features designed for cloud integration are just the beginning of all the changes.

Syncing Across Devices – When you save Office documents online, they will be available to you from any device through Web Apps.  In addition, it will retain the last location where you were working before you saved – down to the letter, cell or image.

SkyDrive Integration – Your work now integrates with the cloud, by way of SkyDrive.  When you save a document, worksheet, or presentation by default will save the item to your SkyDrive account, but you can save locally as well.

Touchscreen Use – Some new Office 2013 features are designed to make working with a touchscreen easier, however, touch integration is somewhat erratic.

PDF Editing – With the new Word 2013, you can now open PDF files, edit them, and the save them as either .docx files or PDFs.  So now you can just open a PDF file and get straight to work.

More Graphics Options – New icons on the Insert tab of the ribbon toolbar will now let you insert pictures from your local PC or from different online sources.
