1. I can access the internet at any time, which allows me to, essentially, browse a database of all human knowledge.
2. I am fascinated by how computers work and love to use programming languages to make them do interesting things.
3. I can't stand playing videogames on joypads. I can't aim properly unless I have a mouse to do it with.
4. It allows me to store vast amounts of information so I don't have to memorize things all the time. Also, it's much easier and faster to use than a pencil and paper, because backspace is much simpler and faster than using an eraser.
