Would laptops be helpful during lectures or classes etc?
I think this will depend a lot on the degree tbh (and well general preferences). I know some people in the more rote learning orientated sciences that used them during lectures to type up notes and such. For me in engineering or maths/physics, it's not as helpful as engineering/maths notes seem to end up as a mess of diagrams, something that you can't do quickly enough in a laptop during lectures.
For tutes however, it's a different story. For engineering/maths they do come in handy, if you need to run a quick simulation using matlab/mathematica or do something in solidworks.
or have the textbook on your laptop so you don't have to cart it around for questions.
So I think it would really depend on the degree and subject. I'm not in biomed, but those I know who are seem to use them a bit for lectures.
