Microsoft Office 365 Home Premium: 3.5 million subscribers
Office 365 Home Premium is a subscription version of Microsoft's Office client software. It is key to the company's mission to reinvent itself as a devices and sevices, rather than a pure software company.
The company launched Office 365 Home Premium on January 29. For $99.99 per year, Office 365 Home Premium allows users to install Office client apps on up to five PCs and/or Macs in total. Users who subscribe rather than buy the single-use Office 2013 complement outright, also are supposed to receive regular feature updates and synchronization capabilities by signing in through Office.com.
