Playing Catch up

On this past Monday, we had a teacher work day and I offered to help a colleague set up their smartboard, projector, and laptop. I had been going on and on about how sweet it was and how use full it will be. I helped them get it working and showed some ways I used the smartboard and I was told that they do not see using this very often and that they give it a C. How do you encourage those who are not easily interested in technology that it is worth it?
