In Pictures: Groovy 1970s consumer tech

The 1970s played host to an explosion in consumer electronics gadgets that changed how we educate, entertain, calculate, and communicate.

Personal Computers

If one were ranking consumer tech achievements of the 1970s, the personal computer would surely be on top. During that decade, computers went from being refrigerator-size machines that cost tens of thousands of dollars to being small desktop systems that sold for under $1000. Three major events of the 1970s helped push the personal computer into the mainstream: the invention of the single-chip microprocessor (the Intel 4004, first on our list of the 11 most influential microprocessors of all time) in 1972, the debut of the MITS Altair 8800 kit (one of our most collectible PCs of all time) in 1975, and the launch of the Apple II (one of the greatest PCs of all time) in 1977.

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.
