Collaboration supported by mobile devices has brought advantages for users and also challenges for software developers and mobile computing devices manufacturers. Every kind of device used to support mobile collaboration has strengths and weaknesses depending on the work context where it is used. The idea is to use a specific device when advantages are most relevant and disadvantages do not affect team work. This paper proposes an evaluation framework that helps developers to identify the type of device that can be used to support mobile collaboration in specific work contexts. In addition, three mobile collaborative applications are analyzed using the evaluation framework. The results of the analysis are then compared with the empirically observed suitability.
