Do you need tablets?

Last week, the case study of my group talked about the 4th screen and the tablets.
This is a new platform for marketing, because social medias like Facebook and Twitter are connected with the tablets. People can receive advertisements in anywhere at anytime. Moreover, windows, android, and iOS is designed for downloading applications. Marketers can advertise in those apps, too.
For consumers, tablets are thin and easy to carry. You can do almost everything on it since more and more companies are designing a USB hub. However, people who have had enough PCs will resist buying a new technology tables. They do not want to learn a new knowledge of using it, and it is sometimes confusing. Plus, it is expensive. If they have enough resources such as PCs, cellphones, they will not consider buying it.
I appreciate my group members' hardworking, and I am proud that we create the slides in such a short time. The collaboration in our group is perfect!~ Thank you!
