Was on a review visit to Princeton with about 12 other people from various colleges and universities. We saw that Princeton was installing boards, I assumed it was whiteboards. I said just now installing whiteboards? No we are replacing all the white boards with chalk boards, because evn Princeton Professors can't tell the difference between a Sharpie and a Dry Erase marker.<p>Everyone in my group stated laughing and I just thought as the guy in charge of classroom equipment, hmm how can we get rid of these $5,000 document readers at my school no on can figure them out.
