The current series is the Latitude E-series, introduced in August, 2008, on the Exx00 revision. All E-series models have the Intel Centrino 2 (Montevina) chipset, as well as some variation of the Intel Celeron or Intel Core 2 Duo processors. The mainstream models are separated into two categories: essential and standard. The essential models are the E5400 and E5500, while the standard models are the E6400 and E6500. The Latitude series also include a number of specialty models. The E4200 and E4300 are ultra-portable notebooks. The Latitude E6400 ATG is a ruggedized version of the E6400, and is Dell's only semi-rugged offering. Even Dell's fully-rugged offering, the XFR, has now transitioned from the D to the E series. The Latitude XT2 is a touch-screen convertible-tablet computer. These models all maintain high compatibility with each other, greatly simplifying IT.
