White boards are in my opinion one of the most important tools developers have. I work for a startup company who found me some free office space at a local univeristies innovation office. The offices here didn't have a white board, nor the cash in the budget too purchase them.

We ended up buying cheap tile board from Lowes which works fairly well; however, if you leave stuff on them for too long it will be harder to erase.

What cheap white board solutions can you come up with? We are trying to figure out if we can coat the tile board with something to make it a little less resistant to staining. But so far our solution costed $30 for two 4x8 sheets. I'm tempted to use this tile board instead of drywall when I get around to building my home office.
