You can download as many or as few of the programs you want, and access or share them anywhere thanks to cloud-based sharing and saving.

Microsoft Office mobile apps are free to download and give you access to basically all of the Suite’s programs, though the particular programs available to you are slightly different between Android and iOS, and between iPhone and iPad (though all give you Word, Excel and PowerPoint). Devices can all access the same documents on the same account at different times, so you can work from basically anywhere using the Office Suite - and you can do it for free if you download the mobile apps. You can get Microsoft Office on basically any device these days - desktop computers, laptops, tablets and even phones.
