technology in the classroom

So I have been reading about all this technology in the classroom and how text books of the future are going to be on the computer and virtually take over traditional text books. Okay the idea sounds great but how can school districts assume that all children and households have a computer. Is this going to be a new requirement for parents to have to supply a computer for their child to attend school? What about the parents that cannot afford a computer?

I'm sure then the next answer will be, well then that student can stay after school and use the computers in the library, well sometimes children cannot stay after. I am not at all saying that this is a bad idea, but all factors need to be addressed and understood. Assumptions cannot be made if we are to make sure students are successful.
