Although it's in place, it's been severely restricted due to irrational concerns over security and other illogical arguments. In order for the buying to even occur (keep in mind this was free for the school), there must be knowledgeable IT people in charge.
This is a much smaller scale here since it was for a high school instead of a college, but you'd be surprised at how incompetent people can be.
Right now in the IT people I work under at the university are smart, but lightyears behind when it comes to good user interfaces and the latest technologies.
