This maybe a taboo subject but I'm trying to make a case for purchasing EZ-B instead of the Arduino for a small scale childrens introduction to robotics. I suggested the EZ-B but have been met with resistance from others who have used the Arduino. Has anyone ever had a similar situation? If so, what "selling" points did you use to reinforce your position on the EZ-B? In other words, what makes the EZ-B better than the Arduino?
