I get a Kick out of KIC!

I am attending a monthly KIC (Key Instructional Contact) meeting at the TIES building in Roseville. Today's topic is student response systems. We have heard about Activotes from Promethean, Quizdom, Senteo from SmartBoard and Interwrite.
Here is another learning curve issue for the teachers, but something that we can consider as a technology that will be here to stay and will become integral to instruction. It seems to have acquired enough momentum because of how well it ties in with effective instructional strategies, supports assessment goals, and also how it can become another source of income for technology manufacturers, textbook producers and others who serve the education market. They are part of a movement towards technology aided interactive instruction and the amount of content that is becoming available for teachers to use, should make them more palatable and accessible for larger numbers of teachers. They also have the potential to save teacher time and give them more data that could effectively impact instruction.
I am going to guess that within 5 years these tools will be much more transparently integrated into classrooms, with some painful hills to climb in between.
Will one format rise above the rest, as Blu-Ray has just done over HD-DVD? the interactivity is changing from the IR (infrared) to RF (radio frequency) to highspeed wireless?
I always wonder about the negatives and the things that will be lost when we choose a path to go down.
Robert Frost spoke of the road not taken...I wonder more about the roads that are taken.
