As a fellow Full Stack Web Developer I would suggest a Mac Book Pro (if you can afford things with an apple logo).
Based on experience I often required processing power (large databases crunches) and more battery hours (especially at conferences or courses).
I still remember my first encounter with an Air, a few of my fellow faculty colleagues brought their Air's, almost all of them remained out of battery before they could show their license project.
As I wrote, it's too heavy...
I read that part, you already decided, my advice was for the readers. I for one don't think it's heavy, I don't jog with the laptop anyway 😂.
The air is more portable,but why carry more around something that you cannot use more (no battery left)
