How would the kids without computers study , or do homework?
There are many families that cannot afford computers or ISP payments.
I'm not trying to sound cold here, but what about the ones who can? In 2001, according to the US Census, over half of the 105 million homes owned at least one computer. I would bet that number has gone up significantly over the last four years, and that most of the homes that have no computers also have no children.
If textbooks are as expensive as I remember -- especially a whole year's worth -- a computer is entirely within everyone's means.
