My favourite piece of technology (?)

In my opinion technology is useful and a piece of technology can be more useful that other piece of technology, but in the end, all aim to make life easier.
In my case, i think that my personal computer it's so useful (and it's my favourite), because I can transport anywhere, and in my free time I can do many things, like read e-mails, talk to my friends in social networks, listen to music, sell and buy things, search for information, etc. I use my personal computer to do work for university too. 

because of its many uses, I ocuppy my PC everyday, to do any of the activities aboved named. I like mi computer, because facilitates many things that I have to do daily. Well, without my personal computer I would a different life, but not a bad life.
