This paper is concerned with evaluation on the participants' use of the two multimedia distributing systems; PC-based podcasting and mobile-based distribution. We carried out two experiments in this paper; (i) evaluation of user's impression on the use of these distribution systems, and (ii) the relationship between download time and users' frustration caused by it. The results of students' questionnaire research revealed that there is a statistic significance between these two systems and that mobile-based podcasting was observed to have more salient factors concerning operability like "easy to operate" and "friendliness", regardless of the difficulty of contents. Moreover, the comparative study on the download time between these two systems demonstrated that users were not feeling less comfortable for downloading materials to mobile devices, although mobiles took longer time to download materials than PC. These results lead us to interesting implications that mobile devices will have a great possibility to change learning environment because they will play an important role in the so-called "blended instruction" classroom environment applying to a traditional classroom setting in the near future.
