Assistive Technology

Hi everyone! I am a special education student at Illinois State University. I am trying to get some viewpoints on different ideas relating to Assistive Technology. Here are a few questions I have come up with. Feel free to give your opinions, I'd really appreciate it!

What are some of the pro's and con's of Assistive Technology being implemented in classrooms today? 

Also, do you think children should be limited to a certain amount of AT devices that they are allowed to use?
