I think than my "favorite piece of technology" is the legendary Play Station 1, because it gives to me a lot of good moments in my childhood, and until present day I played with it, and have a lot of fun.
I got it about six years ago, when my cousin gives it to me for my birthday, but I played with my cousin's PS1 since I got an 8 years old

A picture of my favorite PS1's video game: "The legacy of Kain: Soul Reaver"

I use it to play with my friends and my little brother, and I use it only on vacation time, because I'm an addicted to video games =D
In this moment, my life without the PS1 would basically the same, just I would to find a new enjoy activity with my friends and save the old video games on the memory’s chest.
