Equal Access?

I've been thinking lately. Scary, I know. But I've been thinking about technology and equality. Why is it that some schools have little or no technology, while others are using the latest gadgets and have closets full of technology related items they aren't even using. If technology is a tool that can be used to "level the playing field," then why don't more schools have access to technology? And will this desire for equality and learning, in turn, create a larger gap between the "cans" and "cannots"? Those that can  purchase, use, and learn technology will purchase, learn, and benefit from technology. While those that cannot purchase, and therefore use or learn from technology won't be able to. And won't that widen the gap? 
And this ins't just with individuals. What about schools that can purchase iPads for their students to use or other digital readers? How does a school that is still using overhead projectors even keep up with what other schools are learning from technology. 
While the reality is that some schools and individuals have the means to purchase and benefit from technologies, that doesn't mean other schools aren't providing their students with a quality education. Yes, technology can enhance and enrich what students are learning, but just because they don't have an iPad doesn't mean they aren't getting a quality education. I believe technology should be built into the current curriculum content, not the content built into the technology.
