1199 EUR is not insanely expensive, specially considering that I can put up-to 64GB of RAM in a Framework laptop with a reasonable amount of money, while I would need to pay almost the price of a full Framework laptop to do the same in a Macbook Pro [1]. This is IMO, insanely expensive.
And yes, I can definitely use those amount of memory during mass rebuilds that I sometime like to do in NixOS. I don't even try to do those same workloads in my macOS because they start to become hugely slow once you hit the swap.
[1]: by the way, this get even worse considering that I also need to upgrade from an M2 Pro to M2 Max to have the option to do so. I just did a quote for the cheapest Macbook Pro with 64GB of RAM, and I got a 4000EUR quote for 512GB of storage that is laughable low for something that expensive. At that price, I can get 2 of the most expensive Framework AMD and I would still have sufficient money to get another one of the older Intel ones as a spare.
