A freelancer might be interviewed by a client in Entertainment, Hospitality, Construction, Real Estate or Academia and if they show up with a pimped MBA, all their prospect is going to see is that this person asking for a chunk of cash is using the same ‘puter as their kid, so they lose pricing power or maybe the whole gig. Likewise, a dev might go for an interview with a bunch of Pentium heads who think you need a Razor laptop with RGB keys to be legit and they’re going to want to see at least a 16” form-factor as table stakes. There is some variation between those extremes for devs trapped in a corporate setting, but none of it based in reality, the perception is the reality.
Bottom line: M1-MBA16 (or M1-MBA8) for incremental builds, 16” M2P-MBP32 (or M1M-MBP64) for full development or 16” M3M-MBP128 (or M2U-MS192) for AI/media dev ..the other models aren’t really for devs.
