In Pictures: 10 really small devices that could change the world

From the world's tiniest semiconductor laser to a bee-sized flying robot, these minuscule devices -- many of which cannot be seen by a human eye -- are changing our world.

Digital buzz The next time you're harassed by a bee, look closer. It just might be Mobee, a robotic insect, that's spying on you.

Developed at the Harvard Microrobotics Laboratory, the Mobee (from "Monolithic Bee") can buzz around performing tasks such as surveillance -- or even pollinizing plants. Harvard's mechanical bee weighs about as much as a real one (roughly one-tenth of a gram), is about the size of a quarter and, like a real insect, has a pair of fluttering wings, a thorax and stabilizing halteres (small structures which operate like gyroscopes).

Unlike an insect, Mobee also has a battery, microprocessor, sensors, transmitter and antennas, and is made from 18 layers of different materials that assemble like a child's pop-up book.

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.
