I strongly agree with your last thought, our students will find their learning more relevant to their life styles that they wont refuse to learn as much as in the pass. Even in our site, every time we use the laptops they are engage and so interested on what we are doing than when we don't. They are constantly asking to use their phone calculator which I allow them, they feel more connected to their real world.
As for teachers been at different levels with technology, we simply need training that differentiate their teaching level base on teachers true needs, this can only make it better for the classroom and implementation of technology in the class.
