Not a fan of this for a couple of reasons.

1. I have poor handwriting, especially if I'm trying to jot down a bunch of stuff for ~1 hour straight. Being able to read your notes later is pretty important.
2. Sometimes a lecture or discussion goes over a topic it initially covered 10 minutes earlier. Being able to go up the page and add another line on a word document makes notes far easier to follow than drawing arrows or filling in the margins on a real page.
3. A big part of education is learning how to learn -- stuff like paying attention and self-discipline. Today, that includes learning how to manage your interactions with devices.
4. I can space out just fine without a computer anyway.
