I have. It looks like a normal blackboard that doesn't have any chalk nearby. Smart boards are generally worse, but their chalk doesn't run out or disappear.
- zbentley 9y agoIf your blackboard "malfunctions" (runs out of chalk), it's obvious to a new user what the issue is, and how to fix it (borrow some from so-and-so down the hall, or send someone to buy a pack). If your smart blackboard malfunctions, it's not obvious what the problem is (power loss/issue? Software bug? Something else?) and you definitely can't borrow a few ounces of chalk from your neighbor to fix it.

- marcosdumay 9y agoI have also seen uneraseable chalk boards, and boards where the chalk wouldn't adhere. Besides, the chalk powder is a great health hazard, and the sound is a great distractor. There's a reason everybody switched into white boards, and it's not because of novelty. About smart boards, they are great for remote conferences, and for mixing pre-made content with writing. I don't think they are worth the hassle (unless you do remote conferences a lot), but they are not all downsides either.
- greedo 9y ago"chalk powder is a great health hazard" Nonsense. Some individuals with pre-existing breathing conditions may have those conditions exacerbated by inhaling chalk at unusual levels, but to say that chalk powder by itself is a great hazard is nonsense on stilts.
