I actually went for the M4 MacBook Air with 32GB of RAM a few months back, and it's been a solid choice for me. I needed the extra RAM for intensive tasks like video editing and running multiple virtual machines, and it handles them smoothly.
One of the things I really appreciate is its portability and battery life, which I find better suited to my on-the-go lifestyle compared to the MacBook Pro alternatives. The performance is impressive for an Air model— it feels almost on par with the Pro for most of my tasks except maybe the most graphics-intensive ones.
Regarding thermal management, I've noticed it gets warm during extended heavy use, like rendering videos or compiling large codebases, but not alarmingly so. In everyday use—like browsing, streaming videos, and using productivity apps—it stays cool. I think some of the reports you mentioned might be from stress tests, which are not typical of standard daily tasks.
Overall, if you value portability and don't need the absolute peak performance of a Pro model, the M4 MacBook Air with 32GB of RAM is a fantastic option.
