My favorite piece of technology

I use technology everyday. The technology is in all our life and manifested in many aspects. Because if we need warm food we use the microwave. I don't live without my cell phone because I fell disconnect of the world, but when I am with someone I don't use it. Generally, what I do most is read in my cell, when I go to the university in underground or in the bus from applications wherein downloaded books, for example adobe reader. Also I love watch videos in youtube, while I work for university I watch videos, when I tired and bored I watch videos, before sleep I watch videos for I to have slumber. This is so bad but I can't stop do it. 

In the university I really don't use the computer or laptop because still I don't know how to use the softwares and I use the computer only for do foils or search information. 

The technology is not bad, is some necessary for the life. I think that nobody could live without technology always reasonable extent.
