I'm not sure why the negative tone in this thread. The MBA is an amazing value, and appears to have only gotten slightly cheaper . This is a solid product, that continually receives incremental improvements and delivered at a lower price point (when spec'd out).
The MBA is an absolutely solid product that is actually sufficient for the large majority of full stack devs. I use it (MBA 15" M3) with a large complex TypeScript code base, and it is fast and amazing at 24GB of ram or more. PS. The biggest speedup I got this past year (10x) was switching to native TypeScript (tsgo) and native linting (biome or oxlint).
Worth pointing out that the same thing is true for a $350 windows box. The news here isn't "The M5 Air is a disappointment", it's "Laptops are commoditized and boring".
