It’s pretty obvious that if you have a phone, Microsoft would like you to have its mobile Office apps on it. Thanks to a bunch of new partnership deals, that will be happening for many Android phones, whether you like it or not. Microsoft has buddied up with over 70 phone manufacturers to put the Office apps on phones right out of the box.
Office apps have been free to download on mobile phones for a while. But thanks to these partnerships, the phones will come with Office on them. No need to visit the app store and download them.
