Satellites – the one reliable way to communicate with the outside world

The plane crash survivors must use satellite phones to communicate with a freighter ship passing near the island. The reason for this is because satellite phones link to one another directly over a satellite connection rather than a terrestrial cell site, and are thus able to maintain steady communications with one another even as the island moves through time. As "Lost" executive producer Damon Lindelof told Popular Mechanics, satellite phones aren't susceptible to the island's weird space-time distortions that ordinary communications devices are. This means that if the castaways had tried talking to people on the freighter using a standard GSM connection, they might have had severe lags in the other person's response… or, even weirder, the person on the other end might have answered their questions before they were even asked!

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
