IN PICTURES: 15 current and future uses for drones

For a world already on edge about NSA spying, drone technology is just another reason to keep looking over our shoulders.

It's a wild, wild life In Safford, Arizona the U.S. Bureau of Land Management is using this 36-inch long Raven RQ-11a drone with a 4.5-foot wingspan to fly above the San Simon Valley to monitor the impact of climate change on wildlife. The drone, the same type used for surveillance in Afghanistan, is battery operated, can fly for 80 minutes at 30 miles an hour, and can transmit video or infrared imagery to a laptop nine miles away.

The Raven drone has also been used in Colorado to count sandhill cranes. Drones are also being deployed in parts of Africa to monitor and protect wildlife from poachers.

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.

Steph Mundell


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.
