Though it's still a preliminary version, the performance and document-opening speed from a cold start are better than in previous versions, which deserves a round of applause considering that many features require Internet connectivity. The interface has been enhanced, and is now smooth and easy to use.
In fact, to use many of the tools in the suite, you'll need to log in using your Microsoft account. It also includes an online documents manager that can sync with the cloud, as a big focus in this new version is the use of online services through your OneDrive account. This desktop edition includes Access (database manager), Excel (spreadsheets), Word (text editor), OneNote (note-taking tool), Outlook (email client), PowerPoint (presentations), and Publisher (page layout and design for publishing).
It enhances and unifies visual changes from the 2013 version, adding new online features through Office 365, and also adds new features requested by the users and a general performance improvement for the whole package. Microsoft Office 2016 is the new version of the Microsoft Office suite.
