As with any initiative, good school districts continue to monitor and evaluate its implementation to gauge effectiveness, and to revise and change direction as needed. Such was the case in the Hoboken School District. The one-on-one program was revised in favor of other programs for students in which the laptops could be utilized more effectively.
I'm not sure I've ever heard of a time when a shared deployment was more effective than a 1:1 deployment. The bottom line is that their program lacked vision and leadership from the beginning.
