I love whiteboards, they are much better than paper: more space, nice colors, easy to see, very easy to collaborate on, simple redos. That's actually the biggest thing I miss from going into the office: nice huge whiteboards that cover the whole wall, not the little dinky ones that office depot sells for exorbitant prices.

I found a solution though: Lowe's sells a 4'x8' sheet of whiteboard for fifteen bucks, now I have my whiteboard covered wall in my home office so I'm happy again.
