Abstract: A number of technology adoption models have been developed over the years. Currently, there are ten prominent models which since, their development have been tested in different environments. The models have also been extended by including constructs which researchers perceive to be important depending on the environment. The models are Theory of Reasoned Action (TRA), Technology Acceptance Model (TAM), Motivational Model (MM), Theory of Planned Behavior (TPB), Combined TAM and TBP, Model of PC Utilization (MPCU), Innovation Diffusion Theory (IDT), Social Cognitive Theory (SCT), Unified Theory of Acceptance and Use of Technology (UTAUT) and the Extended Unified Theory of Acceptance and Use of Technology (EUTAUT). Generally these models have been developed and tested in non-African and non-developing countries. This study reviews these prominent existing technology adoption models with the aim of establishing their appropriateness in predicting Desktop Open Source Software (OSS) adoption in developing countries in Africa.
