This study describes a semi-structured interview conducted to evaluate how users with multiple mobile devices choose which device to use. The interviews were conducted at the Chapel Hill Public Library and University Mall with a total of 21 participants. Participants were asked to indicate how frequently they used a particular device, depending on the task to perform and the context. Four follow-up questions asked participants to describe how they originally intended to use their devices, how behavior has changed as they've started using them, if or when they multi-task and to summarize what each device is used for. Results indicated that smartphones are heavily used for a variety of tasks and users continue to find them increasingly useful for their ease of access and pervasiveness. Also, tablet users expressed frustration at the limitations of tablet affordances. More research is needed to determine how self-reporting of usage differs from actual usage.
