The thin-and-light Latitude D600 series, based on the new Pentium M processor, marks the start of an ambitious new corporate look for Dell. Not only has the company redesigned all of its popular Latitude laptops, it has also reworked its docking stations, port replicators, and media modules. The notebooks carry the very latest components, including Pentium M processors and Intel's new 855 chipset. The D600 series isn't always a true-blue Centrino, but it can be. The company offers either the Centrino-completing Intel PRO/Wireless 2100 Mini-PCI card, known as Calexico, or Dell Computer's own TrueMobile Wi-Fi Mini-PCI cards, supporting 802.11b/g or a/b/g. If your corporate budget includes money for a new notebook line, the Latitude D series is a wise way to spend it.
