The spread of mobile phones is the biggest ICT breakthrough on the continent.
In terms of the capacity to use IT, Africa cannot be looked at as a single homogenous region – some areas are still under-developed and some are far along the development path. Most developing regions (and Africa is no exception) abound in examples of systems that are not used for lack of basic ICT education, a lack of secondary equipment, reliable power supply or adequate communications infrastructure.
Standard commercial PCs and IT equipment require "normal office conditions" to function effectively – reasonably temperature-controlled, relatively dust-free environments with stable power supplies. In rural areas, which constitute the greater part of Africa, these conditions simply do not prevail and do not suit the use of the typical, inexpensive, off-the-shelf PC.
