The participant filled out a survey about the applications installed on his or her laptop. We asked each participant to go
down their list of applications, sorted by the installation date.Participants were given 10 minutes to describe their installed
applications, and we instructed them to skip pre-installed applications. For each application, the participant recorded the
type of application, how s/he heard about it, what prompted him or her to install it, what factors s/he considered before installing it, etc. On average, participants were able to describe seven applications in the allotted time.
