I use my Surface with a pen running OneNote as a notebook quite a bit. The main use case for me is as my notebook in Farsi classes but I think it would work well in most classroom situations where you want to take freeform digital notes and perhaps mix them with sketches. When using it as a notebook the keyboard is folded away and having a second screen could be useful, the most obvious use case to me is having reference material on one screen while making notes on the other.
The nice thing about the Surface is that you can use it as a full Windows laptop as well and with the keyboard add on it looks like the Neo should work for that as well. Given these devices are quite expensive but also very portable it's nice to have that all in one functionality, particularly when taking short work trips.
