Exploring Apple

I was playing around on the Apple website today. Exploring more specifically their Special Education link. They state that "OS X Lion" is providing new doors to be open in terms of accessibility for students of all abilities. I question that if every Mac comes equipped with dozens of assistive technologies, why isn't the HRSB or DOE mandating that Macs become the computer for all schools. We have a Dell desktop, and I've looked around on it to see what exists for assistive technology. I didn't find anything, although it could also be a result of my lack of computer skills.  
Apple goes on further to break it's assistive technology into 4 sub categories:

1. Literacy and Learning
2. Vision
3. Hearing
4. Physical and Motor Skills
