This is an interesting development:
Chromebook users looking for an alternative to Google’s set of editing tools can now turn to Microsoft Office, which is finally available on Chromebooks. The suite of office apps—Word, Powerpoint, Excel, and Outlook—has been available on macOS, iOS, and Android devices, but Chromebooks have been left out of the picture until now. Depending on your device, however, it could cost you a few bucks for what most would consider essential features.
