> Could we make a whiteboard+marker that had more resistance? Like some hall effect or something. Sounds too complex relative to just using chalkboards.

I think that whiteboard vs chalkboard is just personal preference/cultural, and that the explanations in the article are just trying to justify it (which is totally fair IMHO). So I don't think that there's any need to "fix" that problem with whiteboards.
