Are Mini Whiteboards Really a Good Idea?

I visit quite a lot of high performing schools that aren't pitiful and particularly bothered about students' exercise books. I just wonder whether mini whiteboards, another potential benefit of them here is for those students who are a bit scruffy. It doesn't matter if you're scruffy in the mini whiteboard, hold it up and now we can rub it off. What do you want that? Yeah, I think that makes sense. There's certainly no reason why you can't make great use of the mini whiteboards as a way to get away from this obsession.
