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.

Thanks for the micro-memories Compared to solid state flash storage, the hard drive may seem like yesterday's tech. However, tomorrow's drives could squeeze in 200 times more data.

Scientists at the German Center for Free-Electron Laser Science (CFEL) have created a magnetic storage unit that occupies 4 x 16 nanometers on the disc. Each of its tooth-like structures is composed of 12 iron atoms, yet can store a single bit of data; the whole structure uses 96 atoms to hold a full byte.

This could lead to 100-terabyte drives, but don't hold your breath -- currently, the structure has to remain below -450 degrees Fahrenheit to be stable.

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.
