Dell Latitude 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. The lines of Dell Latitude personal computers are currently in the "E" series, which is the successor to the popular Latitude D, C, and X series. The Latitudes from the early 1990s up until the C*00 lines weren't in a set "series", instead going under the models CP and XP with modifiers at the end, e.g.: XPi, CP M233. In the past, the "mainstream" line was the 6 series, being
