Michael,
I completely agree. Although a learning curve is expected, you do want the benefits to outweigh the investment in time and resources. If you are adopting a technology that will be of great use to you for years to come, it is a wise investment, but when it affects the class negatively and students are drawn away from the topic at hand because they are struggling with the technology, it's use must be reassessed.
Wishing you continued success in the classroom.
