The World's Fair and Technology: 8 Amazing Highlights

Ahead of next month's 2010 World Expo in Shanghai, we explore tech innovations--from the telephone to touchscreens--that premiered during the Fair's sprawling 159-year history

Electric Dreams

According to Washington University in St. Louis, the 1904 St. Louis World's Fair saw the introduction of the electrical plug and wall outlet. And as the university points out, you still can't have too many outlets.

Electricity remained a major attraction at the 1904 exposition: The fairgrounds and major buildings were lit with electric lights, and electrical machinery drew large crowds. In the years prior, Westinghouse won bids to illuminate the 1893 (Chicago) and 1901 (Buffalo) World's Fairs using Nikola Tesla's alternating current (AC) system, rival to General Electric/Thomas Edison's direct-current technology. In 1893, Tesla also showcased the first neon lights and phosphorescent lamps (predecessor to fluorescent lighting).

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.

Simon Harriott


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.
