We live in an age when the external design of a notebook might be considered, in some cases, as important as the level of computing power it can provide. However, there are also some exceptions, especially when we're talking about power users looking for a portable computing system that will not only deliver a more or less attractive look, but also a very high level of performance, durability (for prolonged use while on the go) and an enhanced level of security (especially when used to work with very sensitive data).

And Dell, one of the world's best known notebook manufacturers, has managed to combine all of the three concepts listed above into a single device, the Latitude E6400 notebook, which arrived on the market in Q1 2008, with its sights set clearly on the business environment.

Without a doubt, the E6400 has not been built for the casual users, those looking for some Instant messaging and Internet browsing at home, accompanied by the occasional games (although we've done that as well during the tests). No, it's been designed from the "toes" up to serve as a high-end work partner for busy businessmen, providing both a very solid and sturdy design, an enhanced level of data security (both software and physical), plus a rather "industrial" and "rugged" look, which, however, won't make too many heads turn (unless you're one true hardcore notebook fan).

Besides the features mentioned above, the E6400 also offers a host of interesting connectivity options, a built-in contactless SmartCard reader, WWAN networking, as well as one really special, removable optical unit.

These are only some of the features that make the E6400 quite an interesting product, albeit for a more or less niche market segment. However, if you want to find out just what design peculiarities this thing has to offer, as well as its hardware performance, check out the rest of our review.
