Se pare ca suita este free in cazul iPhone / Smartphone Android pentru home users iar subscriptia anuala este necesara doar pentru companii:

Microsoft Makes Office Free for iPhone and Android Phones - Microsoft today updated Office for the iPhone and Android smartphones and made the application suite free for home users. Previously, the app required a subscription to Office 365, which carried a monthly fee. iPhone and Android smartphone owners can now open, edit, and create Word, Excel, and PowerPoint files on their smartphone for no charge. Business users will still need to subscribe to Office 365 in order to access Office on their smartphone. The change comes just after Microsoft announced Office for the Apple iPad. Office for the iPad is free to download, but is limited to read-only unless iPad owners subscribe to Office 365.
