Mobile computing represents a need of this decade. Mobile computing is possible with a tablet device, for which there is no clear-cut definition. It is partly because mobile computation field is still an emerging field. Tablet industry is still in its infancy stage and therefore, standards have yet to be defined. Given the limitations, however, a tablet device can be defined as a computing device smaller and slower than a laptop, however larger, and faster than a palm type device. In this research work, factors affecting adoption behavior for tablet device among computer users have been studied. An integral part of the study was to compare effect of the income level on adoption behavior. In this regard, two samples of private and public university students were studied. A modified technology acceptance model (TAM) has been used. Two variables were added to TAM model based on Pakistan’s demographics. A questionnaire was used to collect data. 1000 questionnaires were distributed from which we received 972; twenty two questionnaires were having major missing values so they were separated from analysis. Twenty five respondents were found outliers during data screening; by this sample used in this study is 925. Results were analyzed using linear regression which showed only perceived ease of use and perceived usefulness affected attitude to adopt tablet device. These results were found to be consistent for both private and public universities. Facilitation conditions and price perception play an insignificant role. The results confirmed perceived usefulness and ease of use are the only important factors affecting adoption behavior for tablet device.
