The Dell Latitude D800's 1.7-by-14.1-by-10.8-inch, 7.4-pound case outweighs the thin-and-light cases of Dothan competitors such as the HP Compaq Business Notebook nc6000 by more than a pound. Yet with this girth come many perks: such as a broad, 15.4-inch display; a familiar, desktoplike keyboard; and both a touchpad and a pointing stick. The system also offers almost every port possible, including FireWire, Gigabit Ethernet, S-Video out, four USB 2.0 ports, a parallel port, and even a serial port. The latter dinosaur represents a nod to Dell's long-standing corporate customers who may still use old peripherals based on serial port technology. Finally, the Dell Latitude D800 features a swappable internal bay for its included DVD/CD-RW drive and optional modules, such as DVD+R/+RW or a second battery. Each module works with all members of the Latitude D-series family, helping businesses buy fewer modules to share among employees.
