The greatest invention

My favourite piece of technology, definitely, it is the notebook. I had my first computer (it was a desk one) when I was 8-9, I don't remember it well, but I started as a source of entertainment when I was 10. I remember that in that age I created my first facebook, fotolog and habbo's account (I really loved this game), I used it for playing in internet the most of the time and for searching information for school tasks. I replace that computer desk for the notebook, because it is more comfortable; you can carry it to everywhere and you can do many fun things, like watching movies and series (Netflix it is my new addiction), you can also use it for listening to music and finding new songs, to communicate with other people no matter where they are, I use it for working the most of the time (university task), it is a necessity to have a notebook for studying, I think. 
I use it everyday, it is essential for me, but now I am thinking of getting a new notebook, because my actual notebook is slow and big, so I would like something faster and smaller.
My life without a notebook would be boring, really boring and it would take me more time to do my homework and searching for information (because in the internet this is instantaneous). The notebook it is the greatest invention, in my opinion.
