First lesson of mobile technology

I don't have a handheld device. I hope it won't cause me too much inconvenience in this module. In knowing the limitation of using handheld devices in learning, I think it's really a problem for teachers to design 'mobile learning' stuff for students. However, teachers need to equip and prepare ourselves for various mode of learniong before they are widely usable and applicable in our teaching. We can't just learn the use of mobile technology and be an expert in using them in a minute.
