Unlike previous years when it was priced at almost $500 for the entire suite of programs, Microsoft’s apparently rethought its pricing strategy too and you can get everything for $150 in the Home & Student download edition through, for example,. The entire Microsoft Office 2016 suite for Mac includes Excel, PowerPoint, OneNote, Word and Outlook, though it sounds like you might only be looking for the word processor piece of that (Microsoft Word).
In fact, it’s a cross-platform release and is new for Windows systems too, along with iPad, Android and Windows tablet support and a completely different way of working with OneDrive, Microsoft’s cloud storage system (that competes with iCloud, Apple’s cloud storage system).
You’re correct that Microsoft has just released a completely new, completely redesigned version of its flagship product, Microsoft Office, for Mac systems.
