Hello, I am soon to be a graduate student in mathematics. I currently have a chalkboard (well, a whiteboard covered with chalkboard paint) and I very much like it. I think chalk is fun, and I am particularly fond of how long chalk will last. The problem is that I have a laptop, on which I have all of my textbooks. I just also use my computer alot writing on the board, and I have noticed that I always end up with some residue on the keyboard, even though I feel that I am being cautious. A chalkboard is also more noisy. I was thinking about getting another whiteboard, as I would probably have access to classroom chalkboards in the near future, but I am still put off by how quickly markers die. Is there any reasonable compromise? Are there any super long lasting whiteboard markers anyone can recommend?
