Also mid 30s, just wrapped up an engineering Ph.D at a major state research university. It wasn't CS, but still quite technical. Never once did I see classmates use laptops for taking notes. Maybe it was just my department, but we were pen and paper all the way. I'm a bit astonished that taking notes on a laptop is even a thing. It seems incredibly distracting and ineffective. How does one draw diagrams or write equations?
