I do have cousins who are IT students and they are encouraged to use tablets and laptops in class. I think at some point it was even required. Personally I think it is a great way to learn, even though a tablet and a laptop are not cheap. I also heard that some universities  may start incorporating VR in class. I think this is a better way to learn than the use of laptops and tablets, especially in Science class or even History. Instead of sitting in your desk for an hour and listening to your professor, students will be immersed in virtual reality and learn their lessons quickly and better.
