Current Models
As of 2011 Dell's Latitude shipments primarily involve the Latitude E-series, introduced in August 2008, on the Exx00 revision. All E-series models ending in "00" have the Intel Centrino 2 (Montevina) chipset, as well as some variation of the Intel Celeron or Intel Core 2 Duo processors. The E-Series is currently available with the Second Gen Core i processors using the "Sandy Bridge" architecture. The mainstream models are separated into two categories: essential and standard. The essential models are the E54x0 and E55x0, while the standard models are the E64x0 and E65x0. The E64x0 and E65x0 generally use higher end materials like Tri-metal (magnesium alloy) for the chassis, while E5xx0 lines tend to have a plastic chassis (though the new E5420 and E5520 appear to feature Tri-metal casing ). The E6xx0 lines also generally offer higher-end features like dedicated graphics.
The Latitude series also include a number of specialty models. The E42x0 and E43x0 are ultra-portable notebooks. The Latitude E64x0 ATG is a ruggedized version of the E64x0, and is Dell's only semi-rugged offering. Dell's fully rugged offering, the XFR, has transitioned from the D to the E series. The Latitude XT is a touch-screen convertible-tablet computer. Other models like the 13 and the Z have been added to the line also.
Like previous models, the E series has the ability for a second (3-cell) battery in the modular bay. A 9-cell "battery slice" can also be purchased. The battery slice uses the docking connector located on the bottom of the laptop to provide additional power. As a draw-back, the laptop can not be docked while the battery is in place and the battery requires a separate charger. However, with the inclusion of the extra battery, the overall run time for the E series is substantially greater when compared to other Latitude series computers.

Famous quotes containing the words current and/or models:
“Through this broad street, restless ever,
Ebbs and flows a human tide,
Wave on wave a living river;
Wealth and fashion side by side;
Toiler, idler, slave and master, in the same quick current glide.”
—John Greenleaf Whittier (1807–1892)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
