, Apple's iPad tablet computer was an immedi- ate hit when it was introduced in 2010. The iPad's success spurred other manufacturers to offer their own tablet computers, such as Samsung with its Galaxy tablet. Tablets can be purchased directly from carriers as well as through retail outlets. Tablet computers have the potential to add considerable traffic to networks, create significant changes in computing, and have the potential to replace laptop computers as the second computer in many homes. Their small size also makes them easy for mobile employees to take with them when they travel. As a result of their design, tablet computers have smaller storage capacity compared to most laptops. This restriction in conjunction with their greater portability means it is more likely that people will depend more on cloud-based storage and applications such as those from Google and Microsoft for word processing, spreadsheet creation, and graphics for presentations. Storing documents in a provider's network enables users to access and edit files that were perhaps created on desktop computers from any network-connected device. This provides access to more files on a mobile basis than can be stored in a single tablet computer. Moreover, edits and documents can be accessed from desktop, laptop, and tablet computers, regardless of which device was used to create or edit them. Thus, computing tasks previously accessed on a single desktop or laptop computer can now be accessed over internal, wide area, mobile, and landline networks. At the enterprise level, centralized applications and documents will be located in either the organization's own centralized data center or at a provider's data center. In both cases, employees will access the applications and files over landline or mobile networks. Tablet computers are additionally important because they make video conferenc- ing, streaming movies and TV, and viewing photo slideshows from mobile devices more compelling.
