Really though, is that something you would really do? Would you really pay a subscription fee to Microsoft every month to use their Office products? If you would, then the Office 365 series is what you’re looking for.
Office 365 Home Premium (which is the basic version of the suite) includes the core applications that are included in all versions of Office 2013 — Word, Excel, PowerPoint and OneNote — as well as Outlook, Publisher and Access. For $100 (there’s a one-month free trial period), users can install it on up to five devices (including Windows 7 and Windows 8 PCs and tablets, and AppleOS X computers).
(Note: Other upcoming versions include Office 365 Small Business Premium, which is designed for businesses with up to 10 employees; Office 365 ProPlus, which will include 25 user accounts and 5 installations per user; and Office 365 Enterprise. These will also offer a variety of additional features; there is no information yet on when they will ship.)
