I really only use my laptop for studying, school work, watching videos of lectures which causes the laptop to heat up pretty hot.
The heating up would be my biggest concern.
I am also on my laptop 10 hours a day for studying.
Would a MacBook Air be okay with these concerns or should I get the Pro ?
You’ll be fine with the M2. It handles all you can throw at it. I run 3 virtual machines, Office, Safari with 30-40 tabs, Lightroom and it just purrs like a kitten. I’ve never had it get hot on me. I have a M2/16Gb/1Tb. It’s a beast.
