My school actually requires students to have a laptop, although they did not actually verify we each have one. Our faculty discourages taking class notes during lecture on your computer however - they cite research showing you learn better by handwritten notes vs typed. We're allowed to type notes, just discouraged. I take notes on printed ppt slides, that way I can color code and draw diagrams as I go (and I hear you on the non trad, same!! lol). For a couple of classes during lecture, I will have my laptop open to their ppt so that if I want to reference a slide they are not currently on I can easily do so without interrupting the lecturer, and several students do the same thing.
When studying, I almost exclusively take notes in drawing pads (several of us do and swear by it, especially for anatomy). I use my laptop a LOT though to look up images, access ppts, google concepts I do not understand, and so on. And yes, I bring my laptop every day - on the days I didn't think I would want it, I wound up regretting not having it. Most of my cohort brings their laptops almost daily, mostly to use studying between classes. Actually, none of us type notes during lecture, now that I am thinking about it.
