I need a new laptop for software development. I currently have a 8gb m1 Air and it’s not enough for my needs.

I’m currently running a dual monitor setup + macbook display with a dell Dock.

I intend to get another monitor so will have 4 screens in total.

My Air gets really hot with my current setup. intellij uses 4gb ram alone, docker, browser tabs, VM, teams. I’ve seen the air using 4gb swap from the ssd. It’s slowing down a lot. Some apps crash.

I’m not so bothered about the pro screen or refresh rate, extra ports doesn’t interest me either. However I am interested in the active cooling and great battery life since my air gets so hot. I won’t consider a 14pro as I don’t want less than 15 inch for portability/screen comfort.

Should I pick a secondhand/refurbished macbook pro 16 M1 with 16gb ram/512gb ssd or new 15inch M2 air with 24gb ram/512gb ssd?
