In case you missed it, Jared Spataro recently announced that the Office 365 Home and Personal subscriptions will no longer have install limits on devices as of October 2, 2018. A caveat to this is that you can only be logged into five devices at a time. In the past it was 10 devices in total (across five users for the home plan, or two installs for the personal account).
Additionally, Office 365 Home is upping the number of seats from 5 to 6. While that may seem pretty insignificant, that’s an additional license to software essentially as well as the services that come along with it and a terabyte of storage on OneDrive.
