It's unfortunate to see laptops conflated with "all electronics" here. I benefitted greatly from using SoundNote on an iPad in grad school, which allowed me to make recordings of lectures that I could then annotate in real time. Rather than taking a transcript or feeling I had to record all key concepts, I could stick to noting where in the lecture was an especially important concept, or where I had spaced out and should re-listen. More valuable than any written notes I could have taken.
