I’m non-tech side and snorted at max 16GB for devs. GLWT HP. Concur with the other comment that said it’s a marketing exercise aimed at decision makers.
Edit: I meant, you can upgrade it when speccing the laptop. The RAM is probably soldered.
So if you’re stuck at 16GB, that’s unacceptable for a developer laptop in 2022, I don’t care what logo is on the back. 32GB is the only acceptable starting point.
