I bought a 13” M2 for work (freelance dev) last week. It’s a weight and size thing for me. The 14” (I’ve had one before) seems to just cross the threshold for what I can comfortably carry when I’m out and about.
My impression is that the air can’t “gun it” for as long because of heat. Sometimes I run intensive stuff and I’d prefer the machine to turn the fans on rather than throttle the processor.
With that said, the air is nice. It’s just not worth it to save 160 grams for my use case.
