Dell Latitude E6400 +

Dell Latitude is a laptop brand from Dell, targeted for business use. This means that standardized parts are used throughout the line and are available for several years for support purposes. By contrast, the Dell Inspiron is aimed at the consumer market and its specifications change regularly. Whereas Inspiron may change vendors on components several times over the course of a single model, the Latitude line generally retains identical components throughout its production. This design is intended to simplify maintenance and support tasks for large corporations, allowing components to be easily swapped between models.
