From Einstein to Xbox: The IFA consumer electronics exhibition turns 50

From Sept. 3-8, the IFA , one of the oldest and largest consumer electronics exhibitions on the planet, will be in full swing.

Videophone at IFA 1993

Video telephony, like 3D television, is one of those technologies that has been launched and relaunched several times. At IFA in 1993 Deutsche Telekom presented its "Xitel" analog video phone with this oversize model. The phone had a 2.8-inch display and built-in camera. A pair-set cost 1,990 German marks, which was $1,345 at the exchange rate of the time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

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.

STYLISTIC Q702

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.
