Jaws, Windows Eyes are two of the best screen readers, but they are not free.

The internet is not just for people with sight. There is a lot of information out there. If you don't have sight you can still use it, using screen readers, or keyboards with braille.
You take away the sight aspect and you can still use the internet.
If you are Deaf, you can't hear most of the music(Most Deaf people can hear some. A large majority of the Deaf community can heard jets and lawn mowers and chain saws.) If you are Deaf, you still have some sound. Most of the time it sounds like you are underwater, garbled.
I got off on a tangent there, but you take away sound from music and you have nothing. You take away sight from the internet and you can still use it and get around, using sound.

So blind people shouldn't have braille either. Words were not created to feel them, but to see them with your eyes.
