Yes, Apple screws you on SSDs, so that 2 TB adds a lot. If you need it, and don't want an external SSD (2 TB costs $150), the Framework is cheaper with a slower CPU. Maxing internal storage on a Mac laptop is a bad idea if cost matters to you.

EDIT: I haven't felt the need to spec a programming laptop like that. 16/512 feels fast enough, and 32/512 would have room to bloat... er, I mean grow. But I don't use a local LLM, and I don't know whether the difference between a heavily-quantized thing that fits in 16 GB and whatever you can fit in 48 is significant versus the ones running on absurd data center CPUs.
