My preference is this:

Only my personal view.:)
I have to say, your vocabulary is ... WOW ... I'm really impressed by both of your thoughts and your style of writing. But in the "disadvantage" part, to me, your discussion seemed to be the demerits of computers rather than the Internet. I don't think they are synonyms. Perhaps, you should lay more emphasis on the negative effect the
Internet exerts. For example, since people are indulging in the entertainment the Internet provides, hardly do they communicate with one another, and thereby the relationship between families or friends is weakened. It's my point, but I believe you can write a better one. :)
