Maaaaaan, I do not miss the times when I was developing customer-hosted software. With the shitty SaaS model, we can at least crank up the number of nodes and Bob's your uncle, with the self-hosted software we just had to do the most pedantic microoptimizations because the customer was hosting the thing on an overcooked potato.
I much prefer the MacBooks, even the Intel ones that, judging by their temperature and loudness, probably have a nuclear reactor and a jet engine inside.
