If Apple takes something away, people tend to want it more. We see this in the persistent coveting of space gray peripherals — Magic Trackpad, Magic Keyboard, Magic Mouse 2 — that the Cupertino tech giant stopped selling separately last year after the iMac Pro’s discontinuation.
Following the space gray iMac Pro’s launch in 2018 with matching peripherals exclusive to it, owners found they could sell the dark-hued input devices for mad money. So Apple jumped on that market, charging a slight premium over the silver versions, though not forever. But space gray gear still carries a certain cache.
