The recommendations in this document are intended to improve the experience of the Web on mobile devices. While the recommendations are not specifically addressed at the desktop browsing experience, it must be understood that they are made in the context of wishing to work towards "One Web".
As discussed in the Scope document [Scope], One Web means making, as far as is reasonable, the same information and services available to users irrespective of the device they are using. However, it does not mean that exactly the same information is available in exactly the same representation across all devices. The context of mobile use, device capability variations, bandwidth issues and mobile network capabilities all affect the representation. Furthermore, some services and information are more suitable for and targeted at particular user contexts (see 5.1.1 Thematic Consistency of Resource Identified by a URI).
Some services have a primarily mobile appeal (location based services, for example). Some have a primarily mobile appeal but have a complementary desktop aspect (for instance for complex configuration tasks). Still others have a primarily desktop appeal but a complementary mobile aspect (possibly for alerting). Finally there will remain some Web applications that have a primarily desktop appeal (lengthy reference material, rich images, for example).
It is likely that application designers and service providers will wish to provide the best possible experience in the context in which their service has the most appeal. However, while services may be most appropriately experienced in one context or another, it is considered best practice to provide as reasonable experience as is possible given device limitations and not to exclude access from any particular class of device, except where this is necessary because of device limitations.
