Sure, you've heard of Ada Lovelace and Grace Hopper. But how about Frances Allen, Deborah Estrin or Radia Perlman?

Katherine Johnson: Human "computer"

Katherine Johnson, a mathematician and physicist, worked for NASA as a "computer" from the 1950s until the 1980s. Originally part of a group of women who performed precise mathematical calculations, when she was assigned temporarily to an all-male research team, she quickly proved her value and talent. In 1959 she calculated the flight trajectory for the first manned American spaceflight, and in 1969 she calculated the trajectory of the Apollo 11 spaceflight to the moon. Even after NASA started using electronic computers in 1962, Johnson would verify the computer calculations.

Johnson broke barriers as both a woman and an African-American working in the sciences. Among her many honors, Johnson has won the NASA Langley Research Center Special Acheivement award five times.

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.
