With the ‘Intel-based’ Macs you have different screen sizes, processors, RAM configurations and storage.
With Apple’s other ARM-based products, you only have storage configurations – a base, middle and top level.
Assume that the first ARM-based Macbook comes in two screen sizes (like the iPad Pro) and only offers different amounts of storage space.
I wonder if they will offer processor and RAM options. Current ARM devices do not mention RAM at all.
