Inertia-based questions.
At uni….
**Why is it that when some lecturers set up their powerpoints, it is as though they have never seen this technology before and they have to get students to help set it up?
**Why is it that Mac users at uni have to tell everyone that they use a Mac? So what? They are computers. Computers are very common at university.
**Why is it that wherever there are whiteboards, there are always permanent markers nearby for people to use?
****************************************************************
I know how to get permanent marker off a whiteboard, btw. 
I will add more questions when I think of them.
