good points and bad points

Recently, I often use a computer because I have to do my homework.
I think that good points of using a computer are four. First, we can get a lot of information by use an internet. We also can know about many things. Second, everybody can use it. Only we learn how to use it a little, we use it. Third, there are many computers in many places: library, school and internet café. Then, we can send a mail, make a blog, watch a TV and DVD, and listen to music. And bad points are two. First, it is difficult to use. There are many buttons and a lot of information, so I don’t know which information is right. Second, we can’t use it when it makes an error.129
