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 ?
MBA wins on weight and price. Also, if you’re referring to MBA M2, the screen is more eyes-friendly than MBP (for some people with sensitive eyes). If I were you, I would get MBA either 13” or 15”. Use the remaining money to upgrade storage or RAM (look like you need more storage than RAM).
