Pen input is the one factor that forced one of my kids to a Windows laptop for school (a Surface Pro). It was a required feature for his school. Seeing how much he uses it for note taking, I get it. So yes, drawing is a key feature for schools.

Another school uses iPads with keyboards for the same purpose, so I'm not sure where the school market is for these. Maybe only older kids, but a lot of edu-tech is expecting some kind of touch/pen input.
