Understanding teachers' complaints

Even though I didn't conduct any teacher's training, because the teachers were unavailable due to the ongoing exams, I was able to interview one teacher at Kagugu about their life and job. He is a mid-thirty-year old man who teaches math. When we started the conversation he told me the most important thing that would make his life easier is "getting a good salary". Despite having a wife and a couple of kids, it doesn't matter for him even though he would be assigned to work far from his family. After i noticed how ambitious he was, i asked for his views about XOs. "I was so happy when they announced the deployment of XOs at Kagugu", he told me. At first he wasn't open about his feelings about the OLPC learning project. But later on, he cited all the challenges that keep him from achieving the goals of OLPC.
1. " We don't get trained enough so we don't feel comfortable with using laptops in class, moreover usually some kids know more than we do", some teachers think it's embarrassing.
2. " There are some subjects we don't any idea how we can teach them using laptops" which is understandable, but i think sometimes they oppose using them in anything.
3. "Even though we would use them, we would waste a lot of time, since it takes time to distribute and branch the laptops to the power; mainly because of the new professorial education system, we have only less than 45 minutes in a class"
4. "All classrooms have more than 40 students so it's time-consuming to go over and check if every single student is doing the right thing."

I'm still thinking the best planning to oppose these obstacles but if anybody has a point or a suggestion to make, feel welcome to post them here.
