My hopes did raise a little when the guy mentioned people wanted "modularity", then dropped again when he said that meant a box and a screen. That's about as modular as Apple are going to get, sadly.I’m willing to concede that.
I really wanted something like a stack of Mac minis. You have your base Mac box with an M1 Pro/Max in it, later on you can drop an eGPU underneath it, or another could be some extra SSD storage, another could be ports, maybe an optical drive if you needed it. Like PCI cards but external, and all connected through some great little Apple-engineered interface that just clicks when you stack things together. Then I realised that I think we're moving beyond that sort of setup.
Apple is creating a finished product: "Here's a box that does all these things, and you can have some extra ports that let you connect there stuff that we don't make." They aren't catering to the "I want to change my GPU, and now I want to add 16TB of SSD storage, and now I need a sound card" crowd.
