> Is anyone other than a vanishingly small number of hard core hobbiests going to upgrade from an M4 to an M4 Ultra?
I expect that the 2 biggest buyers of M4 Ultra will be people who want to run LLMs locally, and people who want the highest performance machine they can get (professionals), but are wedded to mac-only software.
It is a bit misleading to do that, but in fairness to Apple, almost nobody is upgrading to this from an M4 Mac, so those are probably more useful comparisons.
