The Emerging Model of Subscription Computing
Subscription computing is a package of computer and networking hardware, system and selected application software, and support services necessary to build and maintain a basic computing platform. The package commonly includes a suite of personal-productivity applications, add-ins, and utilities. Some providers include a wide range of business services through a portal. Subscription computing puts the pieces of a computing platform together as a service, rather than as a collection of separately purchased components.
