Printed materials or digital materials...which I prefer

Living in this advanced high-technology modern world, people seem to chase time and want everything to be done easily. Same thing goes with me when comes to reading. I prefer digital reading rather than traditional reading(printed materials). In my opinion, reading printed materials makes one to stick to the author's idea all the time whereas digital reading will direct us to other links and provide us more relevant knowledge. Besides that, digital reading will be more interesting with the use of hypermedia such as attractive visual reality and motion video. However, some of my coursemates prefer printed materials because they feel comfortable with their books beside them all the time. There are some disadvantages of digital reading, the most serious is the effects on our sightness because of straining our eyes sitting infront of computer for a long period. In short, the preferences of reading materials depends on the individual convenience as well as the types of materials.
