According to
Below are some "Suggested Solutions to Problems" with Technology and the percentage of a sample population that chose the stated solutions...

I think from this list of suggested solutions, we can determine 3 barriers that exist.
1.)  Lack of Knowledge about Equipment:  Teachers need ongoing Professional Development.  Unfortunately, this is usually too costly, and instead they get a on-time professional development session.
2) Lack of Quick Tech Support and Maintenance:  Many systems sink money into technology, but don't have the manpower to maintain the equipment properly.
3)  Make Classrooms Similar:  Schools need to have a standard set of equipment in every classroom before branching out to new pieces of technology.
